Funny stuff, but in reality I hope they realize that if all the free users leave, that could get a lot of content creators to branch out, and they could also take the paid users with them.
I pay for premium because I watch YouTube all the time, multiple people in my house watch it on multiple devices, and we even get use out of YouTube music. It’s worth more to me than all other streaming services combined. But I’m there for all the creators and the content they put out, not for anything else unique about the YouTube experience. All they have on their side is install base, infrastructure cost, and inertia. Those are big things to overcome, but if they drive enough people away things could definitely change.
