I think that it would be ok option but for various reason I think it's only acceptable again if you can opt-out by direct payment.

I think that currently this is issue where both sides are partially quilty. Content creators are creating "dirty tricks" to get profit from their work. On the other hand users expect to everything to be free. Users have this huge gap in their head between "free" and "so-cheap-that's-almost-free".

Just as side note: if we wouldn't need this all high-tech for converting "free users" to $. Maybe some of great minds could think how to solve real problems... instead of "How to sell next fucking Nissan".

Also, you mentioned paying a opt-out payment. Spotify does have premium which removes the ads, is there any reason you don't like that?

Spotify method is fine for their service. However I have understood that total ad revenue per user is roughly somewhere around 5-20$/month(?). This is for all the ad services total you use. So problem here is that currently many paid plans cost 5-10$/month/service (at very least). I think Spotify is worth what they ask and their ad plan is very under priced. However if every service ask 20-100x for paid plans VS ad plans idea about paying everything is not very attractive anymore and this won't work.

Also just like movies and games: if it's easier to pirate content than use it legally you are already lost. I may not to want to pay for every single services by credit card but I should be able to handle this ad-network scale easily.
