Those things can happen, sure, but GP is saying that the term "enshittification" was coined to describe a very specific kind of phenomenon about monopoly internet platforms and their pattern of first building dependency and market power before becoming maximally extractive. It's not supposed to be about just any generic way that software might get worse for its users.

Arguably it was a poor choice of word, but some of us would still like to be able to refer to that specific phenomenon.
