Thoughts on enabling advertisements in exchange for Donuts?

I hate in-game adverts. The game takes a while to load anyway, so having an ad at the beginning would slow that down - a real pain when I'm switching between my main and feeder town. Having a banner at the bottom would make the game much harder to play, especially if you're on a phone rather than a tablet.

If EA implemented something like that without a way for me to opt out - whether it be turning it off and forfeiting the donuts, or paying 79p or whatever - I'd be really annoyed. If a game starts out like that, you can choose to avoid it. If they introduce it now, when people are already committed and have spent money, that's pretty unfair.
