I've seen many games get milked or stalled for money, however, it is pretty hypocritical of people to complain about it if they don't make a game themselves. If you genuinely wanted to oppose the idea of milking games, make your own game then rub it in their face when its finished in under a year or something.
(EDIT
Got plenty of replies from others later in this thread. I'd like to say they're 100% correct and I actually second their opinion. To clarify my stance, I just wanted to say that I don't support this type of supporter milking and blind sheep being herded into a long drought of delayed content. The point I wanted to make is that if you really wanna question someone's morals for shamelessly delaying game development for money, it's best to understand their position as well. They don't HAVE to make this game for you, nor do they have to accept your criticism because, in the end, they're the ones making the game. I do think it's the fault of those who pay $50+ a month for development and then complain when they don't see ample development within the month and do NOT cancel their subscriptions. I definitely didn't use hypocrisy as an example correctly. So instead I'll replace it with this:
If you subbed to the creator, waited 9 months for this update, and canceled within the first 3 months of not seeing an update with substantial content, then good for you. In fact, I applaud you and praise you for it.
However, if you subbed for the 9 months, didn't cancel, and then complained about the lack of content in this update, sucks for you. Maybe now it'll take you the first 8 months to realize that you should've canceled and moved on to a more engaging creator that actually puts out updates regularly.
But hey, if you've got the money to spend, go for it. Sheep are sheep.
