I'd be more inclined to berate Apple for this were it not for the amount of crap that Unix-style tools dump in my home directory.
I count 50 .-prefixed files or directories at present, some of which is from Mac developers who should know better (hello, Adobe, Dropbox), some is cryptically-named gunk from other tools (.vegas, .jmf), some various command line histories (bash, fcsh, mysql, psql, pry, sqlite, irb), and so on.
OS X is nicer than traditional Unix behaviour here - it puts it all in a well-organised ~/Library directory.
On Linux things should go in xdg dirs ~/.config ~/.local and ~/.cache instead of ~ but a lot of old unix software and sadly a decent amount of new software(even guis) don't follow the standard.
I got the impression that he's not upset about all the dotfiles, he's upset that they put them on external media. Most unix programs will only create those in the users home, which is usually not external.
