Open source powers commerce

Most people think of open source software as hobbyist code on the internet, but Black Duck’s 2025 audit data found open source in 97% of the commercial codebases it reviewed. In hardware, education technology, and mobile apps, the share reached 100%. (blackduck.com) That means the software inside a bank app, a factory dashboard, or a retailer’s checkout system usually includes code written outside that company. Companies assemble modern software the way builders use steel beams and wiring instead of smelting everything from scratch. (blackduck.com) The reason is simple: open source lets one team publish reusable code once, and thousands of other teams can inspect it, improve it, and plug it into their own products. The Linux Foundation’s 2025 survey said open source now sits in “mission-critical” enterprise systems, which is a long way from side-project status. (linuxfoundation.org) That is why a defensive post about open source landed with a thud: it was arguing against the idea that open code is fringe or unserious. In 2026, the fight is not over whether business uses open source; the fight is over who gets credit, who pays for maintenance, and who carries the security risk. (linuxfoundation.org) Meta sits near the center of that argument because it has published major tools that escaped its own walls and became industry plumbing. React, released by Facebook in 2013, is still one of the most widely used ways to build web interfaces, and React Native became a common path for shipping one mobile app across iPhone and Android. (opensource.fb.com 1) (opensource.fb.com 2) Meta’s open source catalog now spans hundreds of projects across artificial intelligence, infrastructure, developer tools, security, and mobile software. Its official projects directory shows just how much of the company’s engineering output is designed to be reused outside Meta itself. (opensource.fb.com) Big companies do not open source code out of charity alone. The Linux Foundation’s 2026 return-on-investment survey found companies contribute to cut development costs, speed hiring, improve interoperability, and avoid carrying every maintenance burden alone. (linuxfoundation.org) The catch is that reuse creates shared exposure. Black Duck’s 2025 report said 86% of audited codebases contained open source vulnerabilities, which means the same shortcut that saves engineering time can also import an unpatched flaw. (blackduck.com) That is why companies now build Open Source Program Offices, which are internal teams that track licenses, security updates, and contribution policy the way a finance team tracks invoices. The Linux Foundation’s 2025 report found 92% of those offices are actively involved in open source security work. (linuxfoundation.org) So when someone says open source “powers commerce,” that is not rhetoric anymore. It is a description of how modern software gets built: shared code at the bottom, commercial products on top, and companies like Meta helping write parts of the foundation everyone else stands on.
