If they think it's working as intended then they clearly either don't know how it worked before or don't know how it's working now. I set my UI to 150% and scaled down everything to where I wanted it. Text in the dialog boxes is still tiny. Before you could right click them and scale it up to 140% manually, which made it nice and huge for sitting back away from the TV. Now no matter what setting you choose it's either tiny or slightly less tiny, but the text size itself never gets to that big 140% level.
