Under that logic, all games have false choices, and it's true. The idea is giving you the illusion of choice. Even Visual Novels do that. Not to shit in your game though, I guess I simply won't be playing this game, the unity version is terrible and this one is boring despite some improvements.
A lot of porn games called "sandbox" fall under the statement of false choice. But, there is a difference between an actual sandbox game and "wandering" games, which is what the unity version really is.
Degrees of Lewdity is a sandbox game, where your choices impact your story and you can choose them in (mostly) any order you want, or completely ignore stories or characters. That is not the case in the Unity game where you might have 3-5 different things to do at a time, but ultimately cannot progress until you do them all, that is why it is a false choice. You can't just do the "Summer" story, because it is tied into other stories, they pretty much all are.
But hey, you don't enjoy it, and that's fine, it isn't for everyone. I didn't make it for everyone, I made it for me. Various people have asked for various things to be changed. Some of those I agree with and change them. Some of them I don't agree with and decline to change them. This is one of those things. I personally don't think having extra clicks and hunting for a story improves the game.
