Patreon supporters generally know where their money is going: Straight into the YouTuber's (or whatever) pocket. That's the goal of the contributor and there's generally no particular deception on the YouTuber's part either. I want to give them $5 even if they already have a lot of other $5, because that's the value I'm getting or whatever.
I agree with others that Wikipedia very carefully makes it sound like they've got a sob story where if you don't donate they're going to shut down, so they probably get a lot of donations made with the belief that they're funding Wikipedia, but instead it gets shunted out to something else. Maybe something the donor is OK with, but maybe something not.
