I don't have any issues with my AdBlocker on YouTube?
Also, not to be a downer, but CWS and YouTube are both Google property. If your extension does well then they can coordinate to make your life hard. I experienced this personally (https://thenextweb.com/news/how-youtube-killed-an-extension-...) where there was an implication my developer key would be revoked if I didn't delist.
I still have not encountered any issues with uBlock Origin on YouTube.
There's 3 hypotheses I have for why this is.
1. YouTube has been gradually rolling out the counter-blocking to an expanding number of randomly selected users.
2. YouTube doesn't bother blocking me because I've purchased a substantial amount of content from them. There's little benefit in discouraging me from buying more content in the future.
3. YouTube has done some analytics to figure out that I'm the kind of person who will never return if no ad blocking is allowed and doesn't trust them to keep ads out of Premium.
I don't suppose you've purchased shows or movies through YouTube?
I think I purchased one movie through YouTube a few years ago, but it's been a while. I received a YouTube notification a few weeks ago letting me know that AdBlock was not allowed, but there was no follow-up.
I feel that YouTube is very deeply entrenched in a streaming architecture which makes it challenging to serve ads that are indistinguishable from primary content. All of the pushback against adblocking extensions feels like an unwinnable arms race until Manifest v3 becomes mandatory.
Contrast this with Twitch - where uBlock doesn't impact ads at all. I feel Twitch engineered their service to defeat adblock from day 1. YouTube wants to be in the same position, but doesn't seem willing or able to mirror Twitch's architecture.
I'm pretty sure the answer is #1. Gradual, per-account roll-outs of new "features" is very common on YouTube, and from the people I've talked to, the affected people seem to be fairly random.
uBlock Origin + Firefox here, on both desktop and Android, I haven't gotten any warnings either. My guess is that since I'm paying $100/year for 2TB storage they've decided they're making enough from me.
