I see nothing wrong with a dev changing his mind, as long as he offers options to avoid that content if you don't like it.
I mean, it is his game after all, even if he didn't want to include any more sharing content in the past, that doesn't mean he must be eternally bound to that.
It's especially funny considering the complaints are coming from someone who already stated he isn't a supporter anymore, so like, why should the dev give a damn about what he once told him?
Sharing is not really my cup of tea, I can like some of it, if it really fits the character and the story, but in general it's just not my thing, but as long as I have another option to choose, why not cover as many kinks as possible as a dev?
They want their games to be enjoyed by as many people as possible, and it's not like it isn't also a question of getting that sweet money.
