I agree with you in large part, but you are forgetting that pentalobe tools are not easy to find in some countries. In Chile, which is a relatively developed country compared to its neighbors, I went to a shop to buy a pentalobe screwdriver. It took me a couple of afternoons to find the shop. They quoted me something like $35 for a set of screwdrivers (they didn't sell them individually), or $30 to do the service for me.
