I just watched the rant, and while he is not wrong, I think he is overstating the “elitism” aspect just a bit too much. I think Arch forum members are entitled to their high standards when it comes to people participating in their forum. It’s their home, and if they don’t want to deal with newbies who ask stupid questions, that’s entirely their right and I certainly won’t hold them in contempt for it. Even though it is not something I personally practise, I can understand their attitude: they spent so much time and effort into writing what is probably the best Linux documentation project ever, the Arch Wiki. So, I can imagine how they can take it personally when someone asks a question that is answered there, without first looking there. Unfortunately, newbies often lack perspective, we tend to think that our problem is unique.
Fortunately, there exist other forums for Arch-based distros where newbies are welcomed with open arms (obviously, I really love this one, and the Garuda Linux forum is great, as well. Manjaro forum is also very welcoming to newbies). So it’s not true that elitism is the defining feature of the Arch Linux community or that Arch is unwelcoming to newbies, it’s just that the official forum is… well, a bit strict, to put it mildly 

regarding snaps and similar spyware. So, I installed vanilla Arch. The installation from the terminal was something I’ve never done before, but it went pretty smoothly, apart from a very minor trouble with partitioning the drives from the terminal (but I ‘solved’ that issue by just booting an old Ubuntu ISO and using gparted to prepare the partitions for an Arch install
). Took me about an hour from the start to booting into the GUI session.
Or maybe it’s because I used yaourt to get started! ( A friend gave me a pkg file to get started - as I wasn’t ready for makepkg -si at that point. Anyway - you can’t count on much there.
I sort of understand it, but I don’t think it is justified to the extent they take it…
