Yeah, that's not very reassuring.
You guys remember when you bought a computer and could run the software you wanted, independent of political motives? In perpetuity? Reading excuses like this makes me feel validated for cutting macOS out of my professional workflow. The concept of paying Apple to provide high-quality long term support only works if Apple does better than the free offerings. Free offerings that still run 32-bit libraries, run CUDA drivers and other things Apple arbitrarily flipped the switch on.
