Squeezing the toothpaste tube

For some reason a big deal is made out of squeezing the toothpaste tube from the end versus the middle, but I don't see the advantage.  There's a reason people squeeze from the middle; that's where it's easiest to hold the tube from.  Squeezing from the end is extra hassle.  But let's say you're on the wild side and squeeze from the middle.  What are the dire consequences?  Eventually you have to perform a larger one-time operation whereby you squeeze the toothpaste remaining at the end further along, so you can continue to squeeze that from the middle.  A small price to pay for all the middle-squeezing convenience it allows.

End-squeezers and middle-squeezers alike, though, can we all agree... that toothpaste pumps were a pretty stupid phase?
