For me, the worst part is when they interrupt a video. Anything longer than 5 seconds is also a dealbreaker, often I decide that I dont need to see the video after all when multiple longer ads happen. But then again, I could never stand ads on TV either.

I think whats especially egregious about youtube ads is that they prevent you doing what you came for. On basically all other sites, ads are something in the background, something you ignore. They cannot be ignored if they play instead of a video.

Ah, Telegram gets paid 300 million dollars for this action. Understandable.
