There seem to be two kinds of “Linux users”: those that constantly think about Windows, compare their operating system to Windows, and seem to think only “Linux” and “Windows” exists, and those that forget Windows exists and mostly compare different Unix flavors with one another.
Theo de Raadt had some merit when he said that many “Linux users” seem to talk more about Windows than anything else and don't really like Unix as much as that they hate Windows.
But I also find that the latter group rarely even mentions “Linux” that much, which mostly seems to be used as “not-Windows”.
This article too is mostly about Windows.
