Most of your points are refuted by my last statement, we agree that the story requires a faster development.
1) Almost none of the games you mentioned reach a similar quality to this one. You said that "My Wife's a Star" is as slow as this one. Well, the renders are inferior by far and still is this slow. You mentioned several games done in Honey Select/Illussion. To put some perspective, the dev of Bad memories has worked in both engines, Daz and HS, he already finished one game in HS, and his game in Daz, BM, has not been updated in 7 months. He said that the development in HS is a lot faster, that there's no rendering time, but the quality outcome is clearly lower.
Eva Kiss delivers great quality of course, but in 2D, and it's very difficult to compare such different process. Also, she uses the same layers multiple times, when all characters look at the camera standing while they chat to each other, you don't need to work too much the poses and camera angles doing that.
Games in Daz like Dog Days of Summer and Bright Past do the same, the latter can deliver updates almost every month.
The other games in Daz that you mentioned have significantly lower quality, some of them don't even have a lighting treatment, with the exceptions of Because I Love Her, Deliverance and Free Pass, but the latter is done by two devs, it seems, and that's precisely my point: AWAM needs a team.
2) None of the games I mentioned are slow burn games as this one, they still take similar time to release updates and don't receive the same amount of hate. It's evident, it's because of the slow burn.
3) You should name other ultra slow burn games as this one. Also, the popularity increase the haters too.
4) You said that L&P milked his patrons because they didn't know it will take that much time to finish the story at the beginning. Well, we already know that there are several years left and in this month he got his biggest increase in patrons, 400. In 2019, in all that year he only increased 200.

The opposite is happening.
5) This story uses more renders because is a slow burn. Although, I agree that he could reduce a lot of unnecessary renders in my opinion, but that's a matter of taste at the end, many people defend those "unnecessary" renders.
6) Again, different engines, hard to compare.
