Bloody fools. They don't know what beast they are waking up. Certain portion of ad blocker users are zealots. These people are insane and quite a few of them are quite resourceful. Just a few problems that are going to hit YT:
- torrents and other piracy
- rapidly evolving ad-blockers
- undetectable ad-blockers sitting in a new page layer invisible to page scripts
- visual ML ad-blockers detecting ads no matter how they are loaded
- new ad-free P2P video sharing websites
- influential users discouraging everyone from using YT
- popular content creators moving off YT and advertising other hosting options
