But does it mean you opted out? To me it sounds like you entered undefined behavior territory and probably accepted everything

Consent needs to be explicit or there's no consent. Otherwise, we'd be back in the days of putting a message on the site telling "by using our website you accept our ToS and need to give use your firstborn child".

GDPR is opt in not out. If they're tracking you when you do that they're breaking the law.

Also, they're probably breaking the law.

I live in the USA, the country of caveat emptor and 'who cares about citizens, anyway?'.

If I was a European citizen, then I believe by default I did not allow anything. They would be in abeyance of the GDPR if they were to track or identify me.

If I can jam up even a bit of tracking with a PiHole, ublock origin, privacy badger, Bypass Paywalls Clean, Containers, and more, good on me. Im already inexorably tied to google at the moment, and working to remove myself from their ties.
