Probably those are students + hobbyists + maybe Windows game developers? Or my anecdata is just not representative.

Maybe Zed considered it is worth targeting only Mac audience, as it gives much higher rate of people who would actually buy their editor (i.e. the rate of professional users, who code for living, is higher)? That is my guess, I don't have any data to back it up.

In my experience Multi-Platform apps that start by only targeting a single platform do so because that's the one the developer is using.
