I think it is very obvious that this was not their motivation. Hobbyist hackintosh is barely a blip on the radar. They switched to their own CPU because Intel screwed up, plus they want to increase vertical integration. But of course, it is quite likely that once Apple kills x86_64 macOS, it's also the end of Hackintosh. Apple uses too many proprietary extensions (e.g. AMX) and custom hardware (neural engine, GPU, etc.) to make running macOS on generic ARM hardware easy.
