I usually agree with the author, but not really here. > They contradict Unicode So what? The ligatures are only supposed to look good in my editor, with my config, in the programming language I use and for my eyes only.

It is a matter of context, which the author completely misses. And yes, it's also a matter of taste. Everything design related is in parts taste.
