They still sell the Mac Pro. It costs $6000+ and it's whole raison d'etre is to basically be a box that has PCI-e slots. And a big part of that is GPU upgrades.

Isn't that why folks were so excited for the 2019 Mac Pro? You blame some random Libre Linux distro (which is philosophically against you doing what you're doing!) for not booting on a random laptop with an Nvidia card but who do you blame for a Mac Pro not booting with a GeForce card installed? I just think it's an insane unfair double standard. Yeah, the machine bricking when the SSD is a big problem. Waiting a week for parts or a replacement is ridiculous and you can't even boot off an external backup while you wait. That's awful. Especially if you have any BTO config because a wait is guaranteed. macOS updates are insanely slow. I have timed several at 40+ minutes even for just a point update. In that amount of time I can completely reinstall Ubuntu and get set back up. I have never had a Linux or Windows update take that long even on slower worse hardware. Maybe I could get one that slow if I paired an ancient Atom processor with a 4200RPM HDD or something, not a relatively recent i7 with a fast SSD.
