While its true that SJWs pretty much ruin everything they touch in the case of Patreon there are just as many using it for good things. For example there are several reviewers of niche movies/TV/Music where you can "buy" an episode and choose the topic of that episode (as long as it falls into the niche) and dedicate it to someone, E.G. Todd In The Shadows has a show called "One Hit Wonderland" where you can choose any one hit band from the past 40 years if you wish to buy an episode. I have seen similar things done with reviews of games like World of Planes/Tanks/Warships where the buyer can choose which vehicle is under review next. Some of these reviewers also sell game time, where the person buying can be in the next review by joining up with the reviewer in game.
In these "works for hire" I see no issue as everybody gets the content for free, the one paying the money simply gets to choose the topic and be mentioned or appear in the video. Watching a few of these other than the person being mentioned in the front you'd be hard pressed to tell this from any of their other content so if it helps them continue to make entertaining videos we can all watch for free? I say go for it, especially when you can use it to help those that could really use it, like Chuck at SFDebris whose wife has a serious mental illness which requires him to be a stay at home dad.
