This is a big part of the problem with Patreon. Imagine you are a dev for a second. Let's say it takes you 200 hours of work to produce a medium-sized update. (It's just an example, it doesn't need to be exact.) You are getting IDK say $10k/mo from patrons.
Initially you are busting your ass and you manage to do that 200 hours in 2 months, so you make $20k for that 200 hours of work. But over time you kinda get burned out, other things start to take priority, etc., so the next 200 hours winds up taking you 4 months. But then you notice a strange thing - your monthly take didn't drop by much. You wind up making let's say $9k/mo x 4 months = $36k (almost double) for THAT SAME 200 HOURS OF ACTUAL WORK. So you're making more money per hour of time spent working... by releasing updates SLOWER. Plus at some point you are going to run out of new ideas for shit and have to bring the project to a close, and then you have to start ALL OVER with a new project and pray that it's at least as popular and successful... dragging out your existing successful project and just milking it for all it's worth starts to look like a really attractive option.
So Patreon, by nature of it's inherent cuckery and people continuing to blindly support projects that are not reliable at all about releasing content, literally encourages devs to slow the F down and trickle out content. Of course they can't come right out and SAY this, so they make a lot of excuses based on things that are going on in their lives (the same things that happens in everyone else's lives, the difference being most normal people don't get to work significantly less or take months to years off every time life throws them a curve ball.)
