In bigger letters for those in the back:
As a critiquer, your job is not to “make this piece of writing better” but to understand what the writer wants to achieve and help them to achieve it
Applies beyond writing as well.
Also applies to editing. I was recently talking to another writer whose editor (at a publisher) almost destroyed her desire to keep writing. Writers, know the signs of a shitty editor versus one who actually wants to help you achieve your vision, and don’t be afraid to ask for a different one. (Or fire a bad one if you’re indy.)
