If you are sad that the term #enshittification has escaped the lab and is now used to mean everything and nothing, try the term #reintermediation and see if it captures it better and is more resilient to mutation.
It's boring and it's already a financial term that banks unashamedly think is a good thing, but I don't think #ReUnDisintermediation stands a chance, even if I'd like it to.
Maybe #CaptiveReintermediation retains more of that sinister tone.
