I have not. I never signed up for YT Premium, and I don't really plan to.
The moment adblockers stop working on youtube, it’s as if done to me. One ad per video is acceptable but the way it’s become is too agressive and intrusive and block it all shamelessly. Whenever I want to support a creator I use other channels such as patreon.
I have and have noticed this as well. After the trail it seems the ads are excessive.
