Google squashed most of the competition in a lot of sectors, and the few remaining competitors aren't any better often.
Aside, even if you do not actively use google, google will still be in your life, by tracking and selling you. Already there is realistically no way to entirely "ungooglify" your life as long as you live and partake in some modern western society.
And soon it seems, you will be using a Google browser because you have to, because your bank or employer website or whatever will require their web "attestation" DRM, and will not accept your Firefox, Brave, Chromium, Vivaldi, Opera or whatever attestation.
And if you're hoping for other attestation vendors... Try streaming anything that needs a subscription without using Google's widevine DRM. You will be surprised on how few options there are, not just in implementations but in streaming services that support anything besides Google's widevine.
Google and probably Microsoft and Apple will be big enough browser vendors to be widely supported "attested environments" and attestation providers. Everybody else will bite the dust on that front.
E.g. "x% of websites do not accept Firefox's attestation" will drive more users away from Firefox, and that in turn will lead to even fewer websites supporting Firefox attestation because why spend the dev resources to support it with that measly market share when people can just use one of the big browsers?!
And google knows this very well, from the "works best/only in Chrome" to widevine. They were even able to make MS abandon their browser engine and jump on the google engine train, after all.
This to me is very clearly an antitrust issue that needs antitrust suits and regulation.
