Yes, I think the main problem was System 76 shipping a beta DE with an LTS release, which is why I'm surprised most people focused on shitting on Linus for the problem he is having.
Given that most users are still on Windows, you can tell just how numb most people are to bs coming from their OS, so it makes sense for an average user to try out a popular distro a 2nd time after it didn't work out the first time. Also, this is the 2nd time he's trying it, so calling it his fault for not trying another distro after failing twice is kinda misplaced, isn't it? If he's still on Pop!_OS in the next video, then your criticism would make sense. He's also not shitting on Linux, only showing the problems he encountered. If he was trying to shit on Linux, the perspective of the other two presenters wouldn't be so positive.
Linus definitely plays up the character of someone who knows enough to be dangerous. That's part of the entertainment of his channel. Expecting him to only do things competently is basically asking him to abandon the style of his current content. It's like expecting a serious car review from Top Gear. You're never gonna get it and you shouldn't be expecting it.
