I agree with much, but not everything. Some of it was a bit silly. One thing that I would add is that you fully configure MS-DOS using just a few lines of text in AUTOEXEC.BAT and CONFIG.SYS. And that includes setting up many applications and the user's shell. There was also no mention of FreeDOS. That would be a better OS to bring up if we are comparing to Linux. It has been around since 1994, but maybe that article is old enough that FreeDOS had not yet became the de-facto standard DOS yet.
