Why?  Why are we quoting "unix" and "dos"?  Why not quote "UNIX"
and "DOS"?  What is the reasoning behind this?  Apparently these
are not literal programming strings - or if they are, it's not
clear how they are used as strings.

How does that respond to the cited sentence it follows?

Quoted text might end up with curly quotes.  The question is
why these words should be quoted (using ordinary text quotes),
and if they should (no reason given so far) then why they
should be lowercase.
