I don’t know what needs to be discussed. Everyone owns their code, every project has some kind of hierarchy. Chromium is a project started by google, so Alphabet Inc. has a final word in any decisions. Similarly Linus Torvalds has a final say in Linux kernel development, and Lennart Poettering in systemd. That’s how it always worked, and I think it’s good enough.

What you can do is, you can hard fork a project, than you can have a final say there. This is actually how chromium’s engine started: its Blink engine is the fork of Apple’s webkit engine which is again a fork of Kde’s khtml engine.

Ungoogled chromium is not a hard fork it’s just a list of patches: https://github.com/ungoogled-software/ungoogled-chromium They can override google’s decisions this way, but the more thing they patch the more thing they have to maintain, more work, and more things can break with each update. Afaik it’s similar how all other chromium based browsers work.

Everyone said this for years now. If you care about the freedom of internet (caring about your privacy is secondary) you shouldn’t use chromium based browsers. Stop using it now.

Open source doesn’t mean they have to accept community input. The rights you’re granted are the right to take their code and alter it for your own project, or redistribute it, not direct it.

A lot of corporate owned open source projects choose not to accept third party contributions at all (or at least without giving them actual ownership), because if they own the entire codebase, they can sell different licenses to businesses that may not like some restriction of the open source license.
