I will never ask you why you don't offer a solution. I know that is what design is. Criticism identifies a purpose, design finds ways to satisfy it.
If you are going to identify a purpose, do it well.
always sucks to hear someone perfectly identify and articulate an obscure problem/purpose and then give in to pressure with a "if i had to suggest a solution..."
NO! It's ok to be good at cornering what's wrong, that's a skill
focus on making your criticism sharp. There is so much value in making an undeniable observation about how something is broken or how it could be much better.
If the designers* involved are genuine in their intent, they should not be able to ignore it.
*design is a process of purpose satisfaction, it is not figma or photoshop
design should always be free enough to determine that the purpose is not satisfiable with whatever means is being imposed on the process
commercial constraints should be acknowledged as what they are. They are a layer of circumstance.

@fasterandworse thank you for this thread. I have a pinned post that got a ton of traction that was just me rephrasing the work of others into a digestible series of posts.
I was very frustrated by people asking me what I would do to fix the problem. I didn't reply to any of them, because I don't have a solution that wasn't the point in the first place.
This thread clarified for my why I was so frustrated--fixing wasn't the work I was trying to do.
