I said it over on the SA topic, but I think what changes things a bit about this episode compared to the other crowdfunding ones is that there's a different balance of stupid. The Kickstarter and IndieGoGo episodes are, mostly, filled with complete goddamn idiots. Their idea is dumb, their execution is dumb, they are dumb, and nothing is done because it's all so stupid. It's like Fantendo, Ahhha, or the Idea Wiki in later stages; they've had to temper their brain vomit a little bit, but haven't done it nearly enough.
These Patreon idiots are mostly a different type of stupid; the slightly smarter kind, that has a better idea of what they're doing but hasn't spent enough time in the real world to realize how it works. There's still complete idiots here, just as there was still 'slightly clued-in but still oblivious' stupid in the other crowdfunding episodes, but it leads to a different sort of comedy. It's more partnered with episodes like NaNoWriMo, Troper Tales, and to a lesser extent the people who wanted in on Mars One, who just don't entirely have a grasp of the fact that they aren't special.
I can see being disappointed about that, because it requires a different sort of mindset coming in, and you might just enjoy the complete morons better than the self-important ones (personally I think the self-important ones are funnier on average, but the heights of complete idiots are higher). These guys are just as worthy of ridicule, but for different reasons, and it might be that people who don't like it are having trouble shifting those gears properly.
