I've read this a few times over the last pages. The fact that some people keep repeating it doesn't make it true. In fact, it's absolutely false.
The choices in that poll were not:
1) I keep making Milfy City.
2) I make a brand new thing.
The 2 actual options were:
1) I rush Milfy City's end in 2 more updates in the next few months and then move on to something new.
2) I keep developing MC properly at a slower pace, while starting to work on my new game.
Obviously, Milfy City's fans were really afraid that ICSTOR might just drop the game altogether, so when they were given the choice they clutched at straws and settled for the lesser evil. That is, they accepted to get slower updates (hahaha!) if it meant the game would eventually be completed properly.
Here's the post mentioning the poll results:
