So YouTube is going to make it impossible to watch without ads. Reddit's communities are going dark because Reddit (essentially) wants more ad revenue. Facebook and Instagram have been plastered with ads for longer than they haven't. And we're just a short hop from ads being "Attention required" with eyeballs tracked. I wonder if there's a possibility that this will shake Youtube from it's dominance.
Yes, I'm sure everyone is fighting for an audience who refuse to pay and block all ads. And of course the audience who do sit through ads or pay are therefore not going to switch and stick with YouTube.
So unless you want to burn money, I really don't see a viable business model there. Unless you think you can take the initial hit to grow a big enough audience and then force ads and paid subscriptions on everyone to make that money back.
