If let's say that google charges 1$ (or more, adjust yourself) per gb of stored video, or 1$ per 20gb of bandwidth use to opt out of ads, will it be better?
Speaking for myself, I would be willing to pay YouTube to opt out of ads. I post mostly classical music videos, which are totally ruined if video advertisements are inserted in the middle. (Granted, YouTube doesn't seem to do that to classical music videos quite as much as it used to.)
I'm already paying Vimeo for a low-budget data plan, and I only continue to use YouTube as my main platform because of the extra exposure.
