Not sure it's ignorance, I think it's piggy adapting his mindset, here's how I'm thinking; (the end goal is of course to make as much as possible, those golden Hogan's won't pull themselves, will they?)
It used to be "support=money, the end", but, since "he" moved on from Twitch he has added new claims of "positive support doods!":
Memberships, likes, "I put comments on again guys, for you... (has nothing to do with SuperThanks not being allowed with comments off, trust me)", "gifted memberships are here, Susan finally let go of that sandwich"...
Piggy's an absolute idiot but he knows that his house band "Derich and the dentheads" are even more dumb (maybe gulliblke/easily lead are better words, some of them are just lonely fucks that felt welcome inside the cult as they had fuck all else) and he abuses that and says "Thanks for the amazing support" to give them a feeling they're loved by just giving a thumbs up, thereby making them think: "maybe next time I can give him some money as well, I hope I can!".
Jim Jones would've been jealous over Dave's ability to lead his horde and even more so as he didn't have to run away, Phil fucked the government (which I generally don't mind, just wish it was someone better) and got away with quite a bit of it's money as well, as they basically payed his debt... (Jim Jones, not so much...)
