To me, the first indications that Apple was no longer interested in software professionals were: 1) Removal of USB-A ports, 2) Removal of the ESC key. I bailed out of the Mac world right then. The subsequent software issues (dropping of 32-bit, instability in Catalina, this new MacOS 11) just confirmed my suspicions. The Linux Desktop is still frustrating in so many ways compared to the MacOS, but I can be reasonably productive.
