I see quite a few people are upset that their favorite distro isn’t “officially supported”, but I have two points:
First, on every other mainstream laptop, NO Linux distro is officially supported. Closest I can find is forum posts about Dell laptops on their official forums from 2016, and even then you only receive help from users, not staff. Providing support for Linux is entirely too costly an endeavour (pun intended) for tech companies, so I’m happy to see boundaries being drawn.
Second, “officially supported” doesn’t exactly mean “you’re on your own” even from staff: at the bottom of it all, support staff want to help people, so you may receive a fix even if it’s not official, from an official staff member. See this post.
