People will always wonder why proprietary software a lot of the time wins the day. Shit like this is why, activists will inevitably fuck shit up and throw out the core principle of something like Open Source because of petty grievances. With proprietary software, there is at the very least the illusion of professionalism and the profit motive keeping them from going full retard in a lot of cases despite of the spyware or other bullshit that comes with their programs.
There's a reason why Unity and Unreal prevail over Godot and it's forks, there's a reason why Apple and Microsoft control 95% of the market share in regards to Operating Systems, there's even a reason why Redhat Enterprise is now proprietary. If nothing is done now, FOSS will either rot or it will splinter.
Free software and open-source in general is an amazing thing, but each individual project is too susceptible to its leadership. Far too many people believe it's okay, the right thing to do, and perfectly sane to turn anything amazing they've made into an activist tool, we have seen many cases of that and at an alarmingly increasing rate. Companies have an implicit obligation to keep selling a product to their customers, and an explicit one to their shareholders not to tear themselves down with political infighting, that's a brake many FOSS projects don't have. The Unity fiasco is mostly forgotten about now, its CEO was forced to step down and they added a clause that no runtime fee will happen in any version as it stands now, and it seems like they might be on the right track with 6 to stop constantly releasing half-baked features. Godot's leadership (W4 foundation members) is the opposite of that, stubborn and incompetent, making claims of being AA-ready while constantly covering behind the "hobbyist engine" drivel, you can't kick them off and they decide where the project goes and what gets done, and how. Good luck trying to fork that incredibly opinionated mess, making sense of it. Even if you succeed, you'll be feeding code back to them to port into consoles making money and supporting their decisions. I'll trust a company over incompetent individuals, but competently led FOSS software is almost sacred.
You can see a pattern in many FOSS projects. Some tend to be the source of constant and endless drama of the worst kind while others are far less theatrical and take (usually technical) matters into their own hands and either slowly fade out or wrestle their reasons to exist back into the original project (respectively as an example ffmpeg vs libav, openssl vs libressl). Why is every software adjacent to Wayland, GNOME, Rust, GrapheneOS and so on constantly attracting the most annoying and mentally unstable individuals, some of which have their own thread here, fighting for the most absurd and worthless things? Jumping onto every opportunity to harass developers (see:
serenityOS not too long ago) like a brigade? You hear some news and can already imagine the names of people involved, like many did with Drew and the Stallman report. Because the behavior is tolerated, if not encouraged and signaled by timebombs like the Contributor Covenant CoC(k) that look as if they were designed explicitly to make projects implode on the long run. The GNU Kind Communications Guidelines is not like that, and that's also why the recent report explicitly wants it replaced with that Ehmke-monster one. Then you've also got all sorts of cancer going on in discord and the likes of that, because every single piece of software needs to have one with an extensive moderation team that spends their entire day powertripping about activism and politics--that's the only people willing to perform such a lowly task. I hear it's working well for Hyprland, be careful not pressing the clown emoji button to any announcement.
Apple and Microsoft don't "control" as much "operating systems" market share as you think. That "95%" is a desktop figure, because the gnu/linux environment has never wasted too much effort trying to appeal to the majority of technically illiterate people using computers. Companies use Linux to get stuff done and so do many developers, let alone most of the infrastructure worldwide relying on it. That's one well-led project that doesn't waste time with "problematic" people, go look at some of Torvald's old quotes, altough it's been faltering for the past few years. But it's true it's never been so reliant on those companies, like Red Hat also (possibly the most reprehensible of them), to survive: the bloat is insane and developers paid by those companies have been working a lot on it.
When I think of attempts to subvert software or just ruin things because of ideologies, SQLite also comes to my mind. It should serve as an example in leadership, and they've been attacked for similar code of conduct reasons before.
EDIT: Also.. some have drawn parallels to Occupy Wall Street and how it allegedly collapsed as people with no interest in the movement but all the time and power to fight about identity politics were introduced into it. I wonder if it hasn't been used by government agencies in projects like Tor (see: Appelbaum's "sexual miscoduct") or in the hacker community in general to destabilize it. I don't know if it's worse to be paid to argue about pronouns or not.
