Does it mean that none of the devs/designers in medium.com use Windows? IMHO it's just interesting coincidence, nothing more. Even though I am not Windows user

Does it mean that none of the devs/designers in medium.com use Windows? IMHO it's just interesting coincidence, nothing more. Even though I am not Windows user and I am not for eternal software backwards compatibility (this topic can evolve into a huge rant). Though somehow medium.com staff tries to prove, that having old font is a bad thing and shouldn't be installed today. They released a major update (even calling it version 2.0) and have not it tested it with users (remember that the goal was to use native fonts, so they must have tested it with Android, iOS, OS X, Windows, Windows Phone, Chrome OS, etc.)? Article was very interesting, showing how can long history of computing produce interesting outcomes. But I felt that author is very annoyed by this coincidence, and somehow this is Microsoft's fault and not medium's and IMHO author is not right.
