I think your coursework-only MS needs to be further broken down into those programs that require a BS in CS and those that don’t. There are at least 3 types of MS in that sense. Without this distinction, your article is short-sighted, not realizing that there are actually many rigorous academic MS programs in CS that would not be doable by someone lacking deep knowledge already.

Erosion of the value of the MS is not isolated to CS.

Forget some universities eroding the MS, entire countries are eroding it. If im not mistaken, Italy is a massive supplier of MS degrees.
