I don't really understand the angst against the Wikimedia Foundation.
They are transparent. No one's being conned into donating. As long as Wikipedia is running fine, and is not degrading, and they're not actively harming it, I don't care. People routinely spend money on much worse things. Is donating $3 to Wikimedia once a year really worse than giving 50-100x more to Starbucks?
People get annoyed at them for their massive banners begging for money making it seem like wikipedia is on the verge of being closed down unless you donate despite the fact they have a ton of money they have saved away which could keep wikipedia running for decades. Even long running wiki editors and donators get pissed off with the behavior of the wikimedia foundation as not enough of this money actually seems to get spent on Wikipedia. Kinda similar to the whole Firefox situation now I come to think about it.
If the donation is given on the false belief that the donations are necessary to keep Wikipedia running, I'd argue donors are being conned into donating. And that is exactly the message the donation banners convey.
