“I run Arch btw” became a meme because until install scripts became commonplace you had to have a reasonable understanding of the terminal and ability to read and follow instructions to install Arch Linux to a usable state. “Look at my l33t skills.”
Dislike of Ubuntu comes from Canonical…well…petting the cat backwards. They go against the grain a lot. They’re increasingly corporate, they did a sketchy sponsorship thing with Amazon at one point, around ten years ago they were in the midst of this whole “Not Invented Here” thing; all tech had to be invented in-house, instead of systemd they made and abandoned Upstart, instead of working on Wayland they pissed away time on Mir, instead of Gnome or KDE they made Unity, and instead of APT they decided to build Snap. Which is the one they’re still clinging to.
For desktop users there are a lot better distros than Ubuntu these days.
Both of my grandmothers are dead, but I did teach my aunt to use Linux. She had a laptop that “ran” Windows 10. It would take 30 seconds to open the Start menu. One SSD, one RAM upgrade and one install of Mint later it’s a whole new machine. She can Firefox and Mahjongg just fine.
