In Europe, there are companies that allow devs to use whatever they like (worked for some of those). Linux is more popular among devs than mac, but less popular than windows. I even have a friend working at a company that's 100% opensource, much to their chagrin as GIMP and Inkscape are no Photoshop.

Linux at school might become more of a thing in Germany as Microsoft 365 office online (or whatever it's called) is in a dangerous spot where it might be banned from schools. IIRC nextcloud and owncloud are positioning themselves to replace it and with that, maybe linux on the desktop might be considered. But since they have a problem with "Apple ambassadors" (aka teachers prostituting themselves for Apple), the real danger exists that schools will be more willing to spend money on fancy mac bullshit than linux. Only time will tell.
