People always seethe over the financial decisions of others. I'm no different, but it's important to remember that a lot of people either don't care, actively buy into whatever the various slow devs are saying, or offer support for some other reason completely unrelated.
I'm not even saying the various devs are intentionally misleading people. I'm sure some of them are, but I think most of them aren't. In this case, I happen to think this dev has been perfectly satisfactory in their explanations. I sympathize with their situation. I genuinely wish them the best. I also do not actively support them, because I, personally, expect content for my money. In fact, I expect high quality content that specifically satisfies whatever itch I have to scratch at that particular time.
We all want the same thing: We want devs who crank out lots of excellent content at a fast pace, while simultaneously getting absolute boatloads of cash for their efforts. Unfortunately, that falls short for most games in at least one way.
