Then simply do a FIFA and give us custom sliders. A ton of them. That way we old farts can finally shut up and the under 20s can have their fancy haircuts and tattoos :pIt's not that easy, mate.
They can't go and change things everytime someone complains.
They have a huge amount of fanbase, and everybody wants their own custom game to be made. So they try to address as many voices as they can when it's a speaking majority.
Just take a look around. Everybody wants something to be changed. Some of us may agree on certain subjects, but then again many have their own vision of what needs to be done. Can't please everybody. So they aim at the wider target: "If we do this, then most of the fanbase will lean more towards buying the game" - "If we do that, we may have a better game, but that's not what the majority (*money*) is asking for".
