They still track you? Is there much of a difference? Get an account you only use for YT, I can't imagine the difference in data leaking will be that much greater if they track you just by IP/other fingerprinting vs a session?

You would need a Google account and that requires another mobile phone number burned.

You used to be able to make a google account without a phone number through Android TV. Not sure if that still works.

Google requires a phone number?

Only if you use a bad / risky ip or browser.

What's a bad browser?
