That may well be the case - however the fact that the single shared galaxy state (that everyone experiences and everyone affects) has been a core design feature since the outset means that every player who has bought the game did so with this feature in-place.
To buy a game on the assumption that it will be changed to suit one's personal preference would be a bit presumptuous, wouldn't you say?
I doubt that many truly would have purchased the game on the assumption that it will be changed. However, I would say that it is quite possible to buy a game (or anything really) with a certain feature and not realise its real significance until a later point. They complain. You point to the fineprint and say, "Well, you should have known. You know, you're being a bit presumptuous." That's your choice. I'm just simply sitting here agreeing with them and say, "Yeah, I get it." But I can't do much more than that.
Some could also say that those who resist change (despite one of the core design 'features' being that it was released in an 'in development' state) that would improve the quality of the game (in their opinion) are somewhat stubborn or unreasonable?
