Just don't buy a console expecting to have that control. Here I am upset that I can't get far over 100 fps.
If they locked it at 30 then they probably didn't have a graphics preset that can get the original XB1 or PS4 to 60 fps. Changing that just for the 4K consoles would lead to an unfair battleground, which is not good for a multiplayer only game.
