I see loads of posts that ad blockers stopped working on youtube. However, I still have no ads there. I'm running vivaldi with ublock on Linux and Vivaldi with minminguard on Android (EU based).
Google/YouTube never rolled out new features to all users at once, especially for new controversial features. They always do staged rollout (e.g. 1% of users, then 5%, then 10%, etc), often geographically limited too. That way they can gauge the potential impact of the new features before fully deploying them (e.g. whether the new features would actually increase their projected revenue or actually decreasing it).
That would explain a lot. We'll see how this develops. For me it would be no big loss when adblock detectoon starts to work here. Loads of spare time to get back. ;) (no ads or no content, as I refuse to watch ads)
The moment an ad loads I close the window and copy the link to another browser. I'm not watching ads for a company that is making billions selling my data why they cry poverty because I won't watch ads. Seriously fuck off Google.
There's 3 reasons why you might see this AdBlock nonsense:
YouTube changed something and the filter lists need a bit of time for volunteers to update them
Your auto update of filter lists did not pull the above update yet
Some other addon/privacy feature interferes with ublock or triggers the adblock detection themselves
If you didn't run into any of these yet, you'll have no problems. Also sometimes you might have one of the above problems, but the adblock detection feature may not have been rolled out to your region/account yet, so you're also fine.
I've gone through great pains to do deGoogle myself. Guess I get some benefits nowadays. Free tube to manage my subscriptions.. works well enough for me
