I agree, sadly. I'm in no way saying VanderLord is one of those; I have no idea what's gone on, in either his real life or in his mind. But it's definitely true that this happens far too often. Creating an adult game — whether using Patreon, Subscribestar, another crowdfunding platform, or all of these — is never a get-rich-quick game. There are very few instances of quick wealth, and usually those that seem like it are actually not.
For instance, if you win big in gambling you get a lot of money right after winning. But the vast majority of winners have bet and lost for years before it pays off. Developing adult games is like most businesses: it takes literally years for most to build enough momentum to have real success. Three months isn't nearly enough time before calling it quits if you're to be successful.
