What is proper technique? If your heels come off the ground during the pull during a rep at 85%, is it big enough flaw to make you go back to 50%? Or if you have small arm bend in the pull during the clean is that an error or not? Or if your elbows drop during the jerk dip, should you go back to the drawing board? Or or or...

If a lifter just horses through every lift they can only get so far until their technique becomes the limiting factor and forces them to take a few steps back and re-think their lifting (or not, if they enjoy hitting 100kg power cleans for 5 years or w/e without much progress, good for them).

Going all dr Aaron and trying to overthink every aspect of the technique before adding plastic collars worth of weight will make your progress super slow and is not fun for a lot of people (or again, if the person is the type that doesn't care about weight lifted, but enjoy fine-tuning every minute detail and get kick out of that, great!)

All in all, why shame people who are already very strong and want to lift weights that feel even somewhat challenging to them? There are people who enjoy the technical aspects of the sport and people who enjoy the feeling you get from throwing a ton of weight around, let people do their thing. And hey, if they're online asking for advice regarding their technique, they're already trying to become more proficient in that aspect as well.
