Here's a different idea:

Don't judge people's reasons for donating money. I'm happy to accept people's donations, regardless of their reason for giving it, because who am I to judge what they do with their money?

Telling people who are trying to donate money that their money is no good because their intentions are wrong seems like the most effective way to stop everyone donating money in their tracks immediately.

>at the expense of others.

Maybe we're talking about different things here, but how is it that a net $70MM donation is coming at the expense of taxpayers?

Yeah well those billionaires don't just donate money to you. They'll create some organization that will compete with yours, then donating money to that. Or they come in and say 'ok we want to support your cause to give free internet for the world's poor, but it should only work with Facebook' or some such strings.
