Some people are saying this is not good for competition.

I see it as a positive for keeping Google in check.

Chrome's marketshare is insane. Google could autoupdate Chrome overnight push out some wild update like requiring you to sign in to use their browser or something else like default rendering everything to AMP wrappers for example... who knows / tinfoil hat time.

Now there's a solid and non-disruptive quick switch default that is already installed (sorry FF, Brave) on Windows machines similar to what Apple has with Safari.
