1) NTR is not forced. It's just not inserted where it was originally wanted, which is why some (including myself) aren't entirely happy with the plot and explanation for introducing it in season 5.
2) AI haters abound. Some of them write problems after the fact (faces, fingers, triple anuses, well the art with Clara (penultimate one) is pretty mediocre). Many just come and write - AI is shit, that's it.
3) The game is not abandoned. It's just that Uber is doing a second remake of seasons 1-4. There was already one, which took a very long time (relative to the usual update release time), and now it's remaking what was already remade (partially). Plus Uber mentioned a quick update that was expected 3-4 months after the current one, but Patreon's ban apparently messed up the plans and the update is now in the long box.
In general, the remake is being made for launch on Steam, from what I have managed to note - the action from high school will move to university or college (judging by the background on the art of Clara), will add content with Tiffany and Mary, icons on the map as in season 5, character biographies, a new interface (possibly).
