I get that a lot of devs are so, but I really don't like it when people immediately jump to conclusions like a "Dev being lazy". A very large number of these devs do their AVNs in their spare time. Even if Az did this full time (which I'm not sure that he does), there is a lot that can happen that doesn't equate to laziness or milking. Az has provided posts on Patreon fairly regularly (usually no more than 4 to 6 weeks between posts), and he has also paused billing before, like with Ep 8 or 9 (I can't remember which; maybe both). From everything I've seen, he has been fair to his patrons.
Additionally, I think it's only been the last few years (since 2021 or maybe 2020) that the time between updates was longer. Earlier episodes obviously didn't take as long, or this would've started development back in 2013. This started in mid-2019, so it's been 4 years for 10 episodes, overall averaging to about 4½–5 months per update. Life happens, and availability can change. The dev might have been slowed, but I have no reason to doubt that he will continue and for sure finish this game. I don't have access to all of the past posts now, but I think life has just gotten in the way and caused some delays.
