Actually, I'm fine with tacking on 20 cents if they can't get my item through the machine. That's completely reasonable.
It's when they charge me double because it's too thick that I get irritated.
That's why I created this tool so I can insure that my packages are less than 1/4" thick. If they are unavoidably over, I'll pay my package rate, no problem. But a quilt block can be packaged so that it's the right size for first class letter rates.

As with any business, if product can be processed mechanically, it's more cost effective than needing to be all done by hand.
