I don't think PopOS could be called "obscure". At the time that the LTT video came out, PopOS and Manjaro (IIRC) were the distros to game on, if you wanted up-to-date OOTB working drivers.

Even so, it was hard to take LTT's attempt at using linux seriously when part of it included Linus bitching about how right clicking a list of files on github and clicking "save link as..." didnt give him a copy of the file. It just highlighted how utterly clueless he was and made it clear he couldn't be trusted for the rest of the video either.
