I do agree that consumers, in general, have become pretty stupid. I also acknowledge what you're referring to in terms of "dropping a few good renders". I'm sure we can both think of a few names of devs who are notorious for that and the simps keep simpin'.
As for TTrick, I understand how it can look for some. I talk with him quite frequently.. I know things that are going on in his personal life, and he knows what's going on in mine. Though, I don't think people can fault him for lack of communication. He does post when he has things worthy of posting. And he also pauses payments when he's unable to work on an update due to life commitments. Unlike those milky devs, he doesn't accept payment when he's not working on the game.
The thing about the subscription model is... anyone can choose to stop supporting when they're unhappy. They can also choose to adjust how much they support. You mention full-time pay for part-time work... how do you determine that? If they work at least 40 hours a week on their job that pays the bills... and then use their free-time to work on games, while also spending time with their families as not to neglect them... I mean, how much time a day do you expect a part-time/hobby dev to spend on a game? Do you think a few hundred dollars a month that some devs get will allow them to buy groceries and pay their rent, among other expenses? Even devs that get a couple thousand dollars a month... Apartments where I live can be low-end $1,400/mo to over $5,000/mo, depending on number of rooms, location, etc.
