No reason? You even stated the reason "for promotion". It's OK if you are not aiming for promotions but don't judge others when they do.

We’re not judging you because you want a promotion. We’re judging you because you selfishly make a ton of work for everyone else so you can feel better about your pointless life.
success in this industry is proportional to your ability to not notice or not believe that your work is pointless
