If they want everyone to have the same visual experience, that is their decision and that's something you need to deal with.
If I'm paying $60 for a game, then damned right I do. I'm the customer, it's their job to convince me to buy it. I can go elsewhere, there's more than a dozen games I want coming out this year. But I love rpgs so Skyrim was near the top of my list. That being said artificially limiting the pc is just being mean to the customer because you can. There were higher settings available in the ini when Oblivion came out, but no one could be bothered to take and hour and write in a "very high" setting on the menu. If the Bethesda developers really don't care about me, then I can feel assured in not caring about them or their game just as easily.
