I think some devs actually do appreciate it. At least, they manage to give me that impression.
But the wider community is a bit antogonistic, IME. It's often seen as being disrespectful or meddling, or being a groupie or something.

It's all very "Those who can, code. Those who can't, test."

Especially galling, when someone spouts that crap whose own code is full of bugs and looks like it was written by a bad AI. Because it probably was. LOL
