Getting this "back on track", or at least back to the tangent that you started...

You're making a lot of assumptions that aren't realistically going to become relevant.
1. You're assuming that sponsors dominate the finances of AMē.
I've already told you this isn't the case.
2. You're assuming that sponsors have huge amounts of power.
This is incorrect as well. Anime convention sponsors usually get small amenities, most typically advertising. ATLUS is sponsoring some of the registration prizing, but that doesn't mean they decided the price of passports.
3. You're assuming that sponsors will throw their weight around and screw up the convention.
There's really no reason to believe this. If some celebrity donates $1,000,000 to the Red Cross, that doesn't mean they're suddenly in charge of relief efforts in Japan. When people give money to a cause, they're typically trusting that organization to do the job, not trying to run the show.
4. You're assuming that if some big sponsor tried to throw their weight around, we couldn't or wouldn't do anything about it.
Let's say some company came forward offering lots of money, but demanding that we start charging all attendees just to get in. What makes you think we'd accept that sort of deal in the first place?
I'm going to ignore your Disneyland example, since it's already been pointed out as irrelevant.
