By and large, free and open source software projects don't compete with FOSS projects. If your project has more users than mine, than we both win.
Even if a project is developed and "owned" by for-profit companies, that doesn't necessarily hurt other projects.
Non-free software is the competition. Possibly even the enemy.
@liw I mostly agree, but I'd say that there's one notable exception: the "FOSS" projects with glossy marketing that are planned from the start to eventually become proprietary or otherwise extractive systems, once they've eaten the other FOSS projects, often with false marketing claims. Though initially they're often framed as community projects.
The JS world (and seemingly also Go?) gets particularly many of these, for some reason.
