even if they did someone will fork and remove them

Ayup, hopefully. But there's a cultural aspect to that IMO. For that to work, we need enough people invested in doing that. Which can be hard and ongoing work! Say I fork an app. Unless I want to "hostile take over" the whole devel, now I've got to keep rolling in updates. Sometimes those can interact with the changes I made in my fork and automated merges don't handle it. It can be thankless work.

We're lucky at the mo, with OSS. It's a tech heavy crowd. That helps a LOT to keep the culture from enshittifying. There's a lot of good faith volunteering around. But that's a fragile thing.
