This is a debate that will never end. My 2 cents - pulls are only problematic if a lifter doesn't already have classic lift technical proficiency. There are a million reasons to do them that aren't always that obvious - for example, my lifters right now are doing high pulls from blocks at mid-thigh - but it's to strengthen the back and arms, not to work the pull.
The Chinese, Russians, Germans, Poles, and pretty much most dominant weightlifting countries use pulls in considerable volume. The Bulgarians may not, or at least in such small quantity no one ever heard about it, but that's one country among many.
Are pulls necessary? Of course not. Are they potentially problematic? Sure. Are they potentially beneficial for a number of reasons/applications? You bet.
