that’s not what they were saying.
They were saying there wish there was a way for designers to contribute. Git is a pain in the ass. lets be real. Important, but a pain. Its a bad UI.
Design isn’t the same as code, so the same process and repos aren’t necessarily going to help. that’s all they didn’t say anything insulting. Only that they wish there was a away for designers to contribute. Why is that hurting peoples feelings?
They’d didn’t say they were a dev so your whole analysis is off.
