Not that I disagree, but I find it a bit harsh.

I know many developers who make at least some open source contributions, be it to an existing project or by open sourcing their own.

It has never, ever happened to me that a UI/UX person opened a PR saying "here, I made a logo for your project because I know how".

I think that there is a cultural thing, where UI/UX people don't consider that they have to work for free on the Internet, and software developers have a tendency to believe they should, "for their CV" or something.
