Actually, I'm fine with that part :) For Windows you nowadays need EV code sign certificates in order to be able to distribute without any troubles and -while you don't pay that directly to Microsoft- these certs are significantly more expensive than the "macOS developer tax". Yes, you can also distribute to the Windows App store, which is cheaper (a one time tax). But I'm not really a fan of "App Store's" be it from Apple/Google or Microsoft.
