Because a lot of gamers don't feel fooled. They expected a Bethesda game and got a Bethesda game for all the good and ill that entails.

You're entitled to dislike the game, but complaining that it's not something else is silly. It's like the people who complain about a lack of easy mode in Dark Souls. Sometimes a game isn't for you and it's ok to move on and play something else, but trying to convince other people they're wrong for enjoying it is a fools errand.
