Excerpts from Jerome Leclanche via arch-dev-public's message of January 26, 2021 21:04:
It sounds to me like Google doesn't want Chromium to have the full functionality anymore; and it kind of sounds like they want Chromium to die and Chrome to be the one-and-only. What we want to do in response to this is IMO not just a legal question but also a moral one. I see from the email threads that several other distros have the same issue.
My recommendation: Drop Chromium from the repositories. Give zero official support for Chrome or Chromium. Announce it very loudly on archlinux.org, as soon as possible. Encourage other distributions to follow suit with the exact same action.
If we make a bit of noise, Google may end up backtracking, but if they don't at least users will know what happened.
