I get it. I've been using Macs for 25+ years and I recently installed a Linux distro with KDE on my Mac in preparation for the ThinkPad I ordered after much deliberation (in lieu of getting one of those crappy "touch bar" MacBook Pros) on which I planned to run Linux while staying on MacOS on the Mac. I am almost certain now that I'm going to stick with Linux across the board on both machines. KDE suits me quite well.
It's been a death by a thousand cuts staying with Apple these past few years. iOS is completely locked down (and shows no signs of relenting) and I only see them moving MacOS in the same direction. Their sub-par, insulting hardware offerings only further cement my view that they no longer give a crap about what the Mac used to be. So, like you, I'm out. It was a fun ride. I've been on-board since System 7.
