2006 - 2022: Corporate content hosts are so cheap and easy that no one has an incentive to learn to self-host content, and people who were previously self-hosting content move over to big "social" platforms

2022 - … : Platforms close off in every imaginable way and start taking every opportunity to extract rents from users, benefits that originally got people to move over now gone, but the network effects are such you can no longer switch to open alternatives or convince other people to do so

#Enshittification is not accidental. It's a *deliberate* policy on the part of a platform corporation, to use #ChokepointCapitalism as a way to squeeze suppliers and consumers.

As @mcc reminds us, that happens only once the corporation believes they've locked in one side; when they've got a lock on you and you feel you have no better option, that's when they squeeze you to extract value.
