I trouble wrapping my mind with the anti-Chromium sentiment. Isn’t monopoly a good thing if it’s an open source monopoly? I don’t seem anyone complaining about the Android monopoly for example or the Linux kernel monopoly.
Afaik Chromium is controlled by Google's devs. E.g. Google introduces quasi-standards because they benefit YouTube, without consulting anyone else. It's basically IE again.
You might say ‘just fork it’, but I'll see how you do that and keep maintaining a full-featured browser. That would also make it not a monopoly.
Chromium itself has features tied to Google. The ‘Ungoogled Chromium’ project is dedicated to undoing that.
Likewise Android goes where Google wants it to go.
Chromium might be Google dominated, but it's definitely an open source project. The reviewers I have worked with have been fair and have granted me more access as I've gotten more involved
Microsoft notably has a big presence in the source code and at events like BlinkOn. As each of these folks get their code merged, they gain privs like merge access and start getting tagged as a reviewer in other's change lists
