Why not? HN is for “Anything that good hackers would find interesting. That includes more than hacking and startups” And why make an account just to say this?
I really wonder what's interesting about this, maybe besides the hint that there are VM solutions for macOS. That's not in the slightest intended to be a personal attack.
But HN is weird, I suppose.
I'm not sure why the comment quality seems to be dropping.
