There is a possibly more general phenomenon where a brand gets good reputation and then begins cutting cost and people will still buy at the high price. I don't know if that one has a name or if it's the same concept as enshittification.
From the Wikipedia page about the practice [1]:
> he reduced his costs and increased his profits at the expense of poorer performance [...] so the Muntz TVs were adequate for a very large fraction of his customers. And for those [...] where the Muntz TVs did not work, those could be returned at the customer's additional effort and expense, and not Muntz's. He focused less resources in the product [...] and focused more resources on advertising and sales promotions.

There was a book with that name, years back. Saw a relative reading it and browsed it briefly myself. Probably are more books by now.
