The first shell listing starts with `cd` and `ls`, the former being run in `~`. What does that weird `~` mean? Very strange.

More seriously, their file system is still case-sensitive, and inside /Programs they have `Iptables` and `Fontconfig`, naively capitalized, but also `OpenOffice` and `HTTPD`.

Not to mention that inside each program folder are `man` and `bin` as usual. I'm going to suggest the point of that article is structure and organization, not naming.

Nobody reasonable complains about a three-letter abbreviation you can type with one hand. For a path you're either accessing a lot or never at all, it makes complete sense.
