In my day job, I work on a relatively large open-source non-GUI application

macOS is becoming an increasingly difficult platform on which to release software. We're going down the notarization rabbit hole (which is a nightmare), but given that we don't fit on the App Store, it's very obvious that Apple doesn't want us on the platform.

My suspicion is that they will eventually charge $$$ for a "developer unlock" on Apple Silicon, a move that I think will make both Windows and Linux look increasingly attractive to developers.
