You could easily embed the ad in the video stream, making it impossible to block. Twitch already does this. Youtube could make them unblock able too.

at least with youtube I can pay for the premium and don't get ads. Twitch prime used to do this. They can go fuck off right now I'm cancelling my amazon prime because getting no ads on twitch (on fire TV and mobile) is the only reason I got it
