Presumably the end game is for Google and a few other corporations to control what web browsers you can use to access most of the web. Mozilla may or may not play asking (they did on EME). Linux won't work except maybe for Ubuntu and Red Hat build if/once they get around to adding support for it. That could be a long time since you need a long chain of verifications to pass thru the browser, OS, kernel, boot environment, and TPM to work AND you'll need to convince Google that the chain is strong enough to not be hacked. Ad blockers will be shut out at some point.

And no, you can't just go back to playing flight simulator off of floppies. Your bank, your airplane and concert tickets, heck even your child's pediatrician will require it. Not that doctors are hungrily reading up new web specifications, but they'll be using a medical services platform that relies on some cloudflare defaults that all the security guys like because it cuts down on bots and DDoS.

You'll be left using walled garden operating systems that spy and advertise as incessantly as cable TV.

Maybe a big stink will cause Google to backtrack a little, or make promises they won't and can't ultimately keep. The only real solution is to use the government to prevent users from losing control.
