Honest question: What are the alternstives?
I agree that enshittification is a, well, shitty term, but I know obly it to describe the problem at hand.
Alternstives I think of are walled gardens, collapse of the internet as we know it, lockdown of social media sites, etc. - none of them all that simple and miss the point enshittification has.
Decay is a natural process however that just happens if you don’t stop it. I still think ‘enshittification’ fits it best because it implies a bit of intentionality on the part of the shittifiers.
The term is sticky (ewww) and I think we are stuck with it.
The only other good term for Enshittification I’ve seen used is Platform Decay. It was even coined by the same person who coined enshittification.
