Worse is when ad technology is prioritized and is set up more stably/reliably than the content itself. It’s one thing to sit through an ad before successfully watching something but quite another to put up with that and then see some obscure error code instead of the content you “paid” for with your ad eyeballs. I’ve had things fail 2 or 3 times, each time replaying the same ENTIRE ad without a hitch but then failing to deliver.
This is why people cry no tears when ad companies complain. If you want to stick crap in my way, the experience had better be flawless.
