Oh YouTube, bless your heart. No-one's going to pay for your shit.
Download videos? Why bother when I can use a third party application to do that anyway? Failing that, I'll just fullscreen and use ShadowPlay to record my desktop. No ads? Please, I white-listed the site so the few people I do watch on the regular can get paid. And as for your "exclusive content"... Nice try, but I'm not biting. You're gonna need better bait. Also, good luck beating the people that will download/screen capture those videos, then upload them elsewhere for people to watch.
It's almost like this was designed by committee and you didn't even think this through. Amazing.
