He's talking about Linux neckbeards and gatekeepers, not, say, cultural idiosyncrasies of any given distro.
I used to use an old omakase version of Debian called Crunchbang in uni (https://crunchbang.org/) and there was always someone around to make the remark that you'd only use it if you couldn't read manpages.
Or Dropbox seems pointless because you can build it trivially by mounting an ftp location with curlftpfs + svn.
There's a clear market for "good enough" Linux boxes for coders and casual Chromebook-style usage (Steam Machine style) that's constantly bullied by the "you should read the manpage before posting" crowd.
