One part of the enshittification process that @pluralistic leaves out of his equation is third-party developers. Developers are like the canaries in the enshittification coalmine.
They create a huge part of the value of a platform for both end users and businesses.
Platforms encourage this value creation in the ecosystem, and cherry-pick the best apps to either clone or acquire.
Then, they shiv developers with an API TOS change.
@pluralistic Facebook Platform did this. LinkedIn did this. Google. Twitter has been knifing its developer community for over a decade.
