I let them play ads... The reason for that is they revenue share with the content creators. I would actually gladly go to a twitch-style x bucks a month model where some of the x is divided up by the content creators, but they aren't offering that. I heard they're starting someting like that for other websites, but not youtube
That being said, they've shown me the same exact advert for a restaurant about 30-40 times in a row now and I'm starting to feel like its not worth it. I don't want your 'apps', Chilli's.
