Hmm. I still have my old 2013 MBA that I've used with Fedora, but it's an HD 4000 IIRC. I feel you on Apple's locked down stance to repairs. It was ultimately what pushed me off of OS X. I needed a newer laptop in 2020, and they only sold hardware with non-upgradable RAM and SSDs. So long and thanks for all the fish... I had already replaced my desktop machine with Linux a few years earlier. I used the Mac 70% as a Unix machine anyway, so it was a pretty comfortable transition.
My Air worked great as a stand-in laptop when my System76 Lemur died last summer. Honestly I was blown away by how perfectly usable it still was for basic tasks. Parallel stuff like compiling was slow, but single threaded stuff still ran just great. Heck, I was even using it again yesterday to test OS X builds of my game on older hardware and it ran like a champ.
Eh, guessing from a distance or playing favorites won't be better though. Like I might get grumpy about a C-level guy or investor getting more than their "fair share", but marketing for example is still an important job done by people that aren't paid gobs of money. Without the ability to let the people that would buy it know about your product, it effectively doesn't exist. We all love the story about a game that came out of nowhere, but that's the exception, not the rule.
