One could easily reply an equally snarky answer of “Use a real OS, not MSFT spyware. We got to have some standards, don’t you think?”

WSL is a pretty niche version of "Linux". I would guess that close to 0% of what makes it to the front page of HN had a QA team that explicitly tested it on WSL.

It's pretty self-evident that Linux support can't be expected to mean Windows support. If something is broken in the Windows simulation of a Linux GUI stack you should be complaining to Microsoft, not to the developers of a program that works fine in a normal environment.
