I have no problem with them saying if you want to sit in these sections you must donate $X per ticket. If you want to sit in these sections you must donate $Y per ticket. And so on. Which, of course, they already do.
That is not what they did last time, and it's not what they are doing now. Someone could have donated $2,000 a year for the last 20 years (hell, 50 years). If someone made a one time donation this year of $2,500, they would get to pick their seats ahead of that person who has been around for the last 20 years. And then just like last time, when things go bad that one time donor will bail on you in a heartbeat. Except as we have seen, and we will see again (on a much smaller scale this time), if you piss off the 20 year guy to cater to the one year guy and the 20 year guy leaves, he's never coming back.
