It really doesn't matter that much. If it bothers you THAT badly, just take pride in getting better without using the bar than the players that do use it.
I'm a no bar player for the most part. The only songs I bar at the difficult 10's, but that's because it's more comfortable for me. I CAN do 10's without the bar, I just choose not to.
I don't look down on someone who uses the bar. Though I do think 3x bar on a 7 footer is a little silly, it's their dollar to spend how they want. It has no consequence on me positive or negative.
In other news, this argument is as old as DDR is.
