Chrome also syncs your browser history and passwords with their servers. They have your search history. They have your private email. They have your YouTube history. They have your private documents and photos. They run your phone. They possibly run your laptop. I guess my point is it goes far beyond Chrome. Google is running the Borg hive mind.
tbf they're fairly competent with it, I don't think I've ever had anything Google related compromised. I'm honestly not sure what the better solution is. There's a lot of security theater around this where people will de-google their software and then run random binaries compiled by unknown people on the internet instead
How about a browser company that syncs your data on their servers but doesn’t examine it. Even better, they couldn’t do that even if they wanted to, because your data is encrypted on their servers. That company has also never been compromised. Does that sound better?
