Drew...doesn't, actually, use much of it at all. I don't like the article, but you picked the one person who basically lives by what he rants about.
Let's be specific, then, and exclude any software that is built with GNU make? First thing that goes is the Linux kernel (which can only be built with GNU make). As far as I know, Alpine still relies on the Linux kernel, so that's out.
Pretty far, ask Android, ChromeOS and any BSD user.
Most BSD users I know (including most command line macOS users) do install GNU coreutils.
Nobody I know does. So not a great argument, really. BSD coreutils are fantastic.
BSD utils balk if you get the order of command-line switches "wrong" (an attribute shared with the Git CLI). The time wasted dealing with that alone is worth installing the GNU utils.
Why would you install GNU coreutils on a BSD? Isn't the whole point that it's an integrated project?
For example because BSD POSIX utilities lack some particular flag that you want.
