The problem is probably cause people are generally not patient, by average. So when TD is taking SUUUUUCH a long time to even get an update, no wonder people might feel like they don't want to invest or put time into waiting further. I get it, i really do. But the reality being is that when you are developing something entirely on your own, despite using RPGM as the engine, making original CG content and iterations to the Engine with their own spins and designs, this will take an absolute ludicrous amount of time to develop, much less finish it.
TD WILL take a few years. And will take longer the more content is planned or if the Developer, JimJim feels like it lacks something or wanna fix/change something. I refuse to belittle JimJim for anything. In fact, i admire this passion and fervency to make it as good as possible before finish line. People leaving or getting upset isn't his fault. It is the effect of impatiency and how fucking petty and entitled human beings has become to think life is so easy to just make something in a short timespan for them to consume in mere days, if not hours. My issue is Modern Human is a demanding brat with the attitude of a spoiled psychopath. Disconnect yourself from your boundless hunger, test your patience as far as you can, and if you can wait for a finely made dish and eat it slowly, you will feel true euphoria. Not the muck you expect.
You get low quality Chinese crap if you keep asking for more and more and more, in larger quantities and never satisfied. Time, money and resources is required to make something good. Time being key here, and Time is a limited resource.
If this make any sense to you, then good. If not...well, at least i tried to explain this in the most blunt and proper manner i could manifest.
