Still, what’s wrong with ChromeOS? Did I miss something important? Beyond Google dropping ‘don’t be evil’ obviously.

A quick look through some of the privacy communities will give you an overall vibe on what Google is doing. But overall, they're getting monopolistic.

They're requiring all android developers register their identities with them or they'll be blocked on all Google'd android versions (which almost all Android phones ship with). They're also datamining everyone more and more each year, just like Facebook.

And they're using their influence over Chromium to force adblock blockers into every Chromium browser. And the only non-Chromium browsers are Firefox and its derivatives

And by far the worst one, they bought out ReCaptcha and they just rolled out an update that requires verification with a device that has either iOS or stock android. It doesn't support deGoogle'd android like GrapheneOS or LineageOS, and it doesn't support desktop. So now any website you visit that uses the new version of ReCaptcha requires you to verify your identity with a phone, even if you're accessing the website on desktop. This is so they can link all your systems to your identity

If you value your privacy, you should work to get your digital footprint off Google's software as much as possible
