Not really, basically every youtuber worth his salt has a donate link somewhere on their channel and says "Not asking, just saying" in some form or another. Hell, even I do. The problem is that it's a one time thing. It's something the fan has to go out of their way to remember to do if they want to do support the artist.
Patreon is more like a voluntary subscription fee, I guess is the best way to put it, (It's early and my brain still isn't awake so that might not be the best way to put it). But it's a way for fans to say "Yes, I would like to support you on a regular basis." and not have to be constantly donating manually. Honestly Jack's "Kickstarter for continuous projects" is probably the best way of putting it.
