I'm going to fling that response right back at you. "Enshittification" is not a generic term for "update I don't like", it describes a specific dynamic that happens when a company inserts itself as a middleman into a two-sided market. arXiv could get worse in other ways, but enshittification in particular can't happen to it, that's a category error.

I think you should offer better thoughts instead of mad-libbing in buzzwords where they don't apply. Enshittification is actually a useful concept, and I don't want it to go the way of "FUD", which had a similar trajectory in the later years of Slashdot where people just reduced it to a useless catch-all phrase whenever Microsoft said anything about anything.
