Yeah, a very powerful echo chamber. Those are "Notice me! Please notice me!" behaviour, they are racing with each other to be the best fanboi. You can also see very similar behaviours around Ponzi Schemes, Pyramid Schemes even though scamming is much more obvious.
Few of them are aware of the scamming business, but they can't help themselves. They are in deep with months of payments and trying to make themselves believe that everything is gonna be awesome in the end, nothing is gonna be in vain!
Some of them are just desperate and/or hardcore fanboys, really worshipping him and won't ever question the situation as long as he feeds them with some nice words, not even promises.
Others are just brain dead or have too much money and doesn't give a fuck (or forgot) . Let's say he stopped posting and his patreon became dead for at least a year, they will still continue to pay money.
There are probably some newbie patrons, not aware of the situation and waiting Morpheus to open their eyes.
BTW being a fan of a dev and showering him/her with compliments isn't a bad thing as long as the dev is a hard worker and honest.
Solution is so simple; just pause your pledges for a month and next month you will see that he's working his ass off and releasing new versions like crazy. All you need to do is write a post in discord or patreon anouncing that you're gonna pause your payment and want others to join you. Then hundreds of smart patrons joins the cause to teach a lesson to the dev and... yet impossible! Unfortunately...
So more money for the dev, more fun (or awe) for us, more devotion for his/her cult.
I also don't care about this game for at least a year like Kristof29, but I like reading comments in this thread and similar other threads like Dual Family, Milfy City, AWAM, etc time to time, it's like a fun documentary/mocumentary.
