Well there are 3 branches.

Aparently there is a way, however to make it more of a mess.

I downloaded chromium stable, aparently a few places have autobuild sites.

Bar a few api keys needed for features, chromium is the same as chrome without some of the google features, and edge with the microsoft features.

Apart the only reason a user wouldn't use chromium over chrome or edge is that there are no official binaries published and it doesn't seem to autoupdate itself.

However, chromium standard form can be used by anyone so its going to be an interesting year.
