Open source software adoption is hitting record highs.
49% of IT teams are actively increasing their reliance on open source to build applications. That’s the headline. That’s what the press release wants you to focus on. But before you pop the champagne, there’s a problem hiding in the second sentence of the actual survey data—and it’s way more interesting than the marketing angle.
The Maintenance Trap Nobody Wants to Talk About
Here’s the kicker: 47% of staff spend 75% of their time on maintenance. Let that sink in. Three-quarters of their week. Gone. Vanished into the void of dependency updates, security patches, and compatibility fixes.
This isn’t progress. This is a trap dressed up as innovation. Teams are adopting open source at breakneck speed—attracted by the promise of flexibility, cost savings, and developer freedom—only to discover they’ve inherited a maintenance nightmare that consumes half their engineering budget. It’s like moving to a beautiful Victorian mansion only to realize the plumbing is held together with duct tape and prayers.
And nobody talks about this. The open source community loves to celebrate adoption metrics. Adoption metrics make good graphs. But maintenance burden? That’s boring. That doesn’t fit on a slide at a vendor conference.
Why Are Teams Drowning in Maintenance?
The answer is deceptively simple: open source ecosystems have become absurdly fragmented.
Developer teams aren’t using one or two well-maintained libraries anymore. They’re stitching together 50, 100, sometimes 200 open source dependencies—each with its own release cycle, its own breaking changes, and its own security vulnerabilities. Add in the fact that many open source projects are maintained by exhausted volunteers working in their spare time, and you’ve got a recipe for technical debt that compounds faster than compound interest.
Then there’s the supply chain risk. Every dependency you pull in is a potential attack vector. Log4Shell taught us that one horrifying lesson. But the survey doesn’t dwell on this—it just mentions that AI threats and regulatory pressure are complicating the landscape.
“Open source adoption is surging, with 49% of IT teams increasing usage. However, 47% of staff spend 75% of their time on maintenance.”
That’s not a sustainable equilibrium. That’s a warning sign flashing in neon letters.
The Regulatory Squeeze Is Just Getting Started
EU regulations like the Cyber Resilience Act (CRA) and Digital Operational Resilience Act (DORA) are tightening the screws on open source maintainability—and most teams aren’t ready for it.
CRA, in particular, treats open source software providers like any other software vendor. That means liability. That means security obligations. That means the volunteer who maintains your favorite logging library in their evenings might suddenly be exposed to legal risk. Good luck with that.
DORA focuses on operational resilience for the financial sector, but it’s setting a precedent. If you’re using open source in regulated industries—healthcare, finance, critical infrastructure—compliance costs are about to explode. Teams will need to audit dependencies more rigorously, document security practices, and maintain software that previously lived in the “move fast and break things” zone.
The practical upshot? More maintenance burden. More audits. More gatekeeping. The velocity gains that open source promised are slowly being clawed back by regulation.
Is Open Source Still Worth It?
Absolutely. But not for the reasons vendors want you to believe.
Open source is worth it because you get transparency. You get the ability to fork, modify, and own your stack when proprietary vendors pull the plug or raise prices by 40%. You get access to innovation that happens at the edges of the industry, in communities, not in corporate R&D labs. That’s real value.
But the value comes with operational complexity that most organizations drastically underestimate. You’re not just adopting software; you’re adopting a maintenance obligation. If your team doesn’t have the bandwidth or expertise to manage that—which 47% clearly don’t—you’re playing with fire.
What Should Teams Actually Do?
Stop treating open source adoption as a binary choice between “use it” and “avoid it.” Start thinking about sustainability.
Ask yourself: Which open source dependencies actually matter to your business? Which ones can you reasonably maintain or contribute back to? Which ones are you only using because they were convenient? Then cut ruthlessly. Yes, this goes against the developer instinct to “just add another library,” but it’s the only way to keep maintenance costs from spiraling.
Second, if you’re adopting open source in a regulated space, hire or train people whose job it is to understand the security and compliance implications. Don’t treat this as an afterthought. Third, contribute back when you can. Open source maintainers are drowning in work. If you’re building on their foundations, put some weight into helping them sustain those foundations.
The survey didn’t frame it this way, but that’s the actual story here. Open source is phenomenal—when you approach it with eyes wide open about the costs involved.
What Does This Mean for the Industry?
The current trajectory is unsustainable, and everyone knows it.
Either we see a shift toward better funding mechanisms for critical open source projects (the Linux Foundation’s approach, though imperfect), or we see a slow consolidation where only corporate-backed open source projects survive. Or we see more burnout, more abandoned projects, and more security disasters.
AI threat detection tools might help with security scanning, but they won’t solve the underlying problem: humans are still required to maintain, review, and patch open source software. Automation can catch vulnerabilities faster, but it can’t write the fixes or make the architectural decisions about when to upgrade versus when to stick with a stable version.
What’s fascinating is that the survey touches on all of this—AI threats, regulatory pressure, adoption surge, maintenance crisis—but doesn’t connect the dots. The real story isn’t that open source adoption is increasing. The real story is that the open source community is at an inflection point where the old model (volunteer-driven, barely-maintained software used in production systems) is colliding with a new reality (AI-powered attacks, regulatory requirements, supply chain security).
Something has to give. Probably soon.

Frequently Asked Questions
Why do teams spend so much time maintaining open source dependencies? Open source projects often have different release cycles and breaking changes. Teams need to constantly update dependencies for security patches, feature compatibility, and to stay compliant with regulations like CRA and DORA. Many projects are maintained by volunteers with limited capacity.
Will AI help with open source maintenance costs? AI can speed up vulnerability scanning and detection, but it can’t eliminate the human work of reviewing, patching, and testing code. It’s a helpful tool, not a solution to the underlying staffing problem.
Is open source adoption slowing down because of maintenance burden? No—the survey shows adoption is still rising. But this suggests many teams are adopting without fully accounting for the long-term maintenance costs, which will catch up with them later.
