Earlier quoted context omitted.
The internet for the average person has converged to a handful of products and services. Your point being? People prefer centralised stuff since it takes care a lot of stuff for them. They dont actually care all that much about technology that yield decentralised outcomes. I know that may be difficult for many here to comperehend.
People prefer centralized services until they enshittify, after which people move to the next thing, thanks to the decentralization.
This does not quite follow. Care to explain more? What I observe in practice is that people move from one centralized service to the next centralized service (e.g., X->BlueSky) but rarely from centralized to decentralized.
