I'm not a prescriptivist over any sane time scale (say, 5-10 years and upwards).

But here's what you're basically implying:

A writer was thinking about the ways things get shittier, decided that there was an actual pattern (at least when it came to online services) that came up again and again, such that "shittified" or "shittier" didn't really describe the most insidious part of it, and coined "enshittification" as a neologism that captured both the "shittier/shittified" aspects and also the academic overtones of "enXXXXication" ...

... and within less than 3 years, sloppy use of the neologism rendered it undifferentiatable from its roots, and the language without a simple term to describe the specific, capitalistic, corporatist process that the writer had noticed.

I can be anti-prescriptivist in general without losing my opposition to that specific process.

It's already happened to "vibe coding," which no longer refers to the specific process described by Andrej Karpathy but any use of AI assisted development.

The process of language drift is accelerated exponentially by the internet. 5-10 years and upwards is an obsolete timescale, these changes can happen in months now, sometimes faster depending on the community.
