I don't like to make random assumptions, but it reeeeeeeally seems he's milking his patrons as hell.
Let's be honest: The development speed of this game has been a popular topic of jokes for years (I almost said "generations"), the latest few short updates won't change that. I believe it was about a full year that we could not repair Elena's phone. We got some naughty scenes with Alex but story progress almost stood still for a long, long time.
However ... the dev is known for progressing slowly. His previous game was no different. His patreons know very well what they are paying for and what release intervalls they can expect.
If they are not happy, they will stop paying. But as long as they are ... just let them. Who is not one of those who actually pay, should not be concerned about dairy farmers.
And lets be honest ... the night scene with Kate is something you don't find in any other game. If the end result contains more like this, it's worth the wait.
