1. Dont pretend you haven't done the same before, otherwise why are you on this page in this particular thread
2. Some people dont have enough money to pay on patreon every month, and its sometimes hard to tell which month will have a (for you) significant update and which doesnt. I know its just 1$ to start with, but if you got a couple of devs you support you have to juggle that financial weight, especially if you're a student or have a low-paying job
3. It might sound stupid, and yes from the POV of game devs its annoying that pirating exists, but the game will be pirated anyway. Better its done here with feedback and the chance to actually get some supporters. I found a lot of good creators through this site that I ended up supporting every once in a while. Its free real estate really, even if you got a lot of leeches (yes, guilty on my account) playing your game for free, its still spreading the word about your game and making people aware it exists, which leads to some people supporting the devs long- or at least short-term.
Thats only my opinion though.
