You're still missing where I'm coming from.

> Without Section 230, your aunt would take down her knitting pattern discussion website/chat room/mailing list/whatever within half a day, with whoever it was posting something objectionable (or just off topic) and when your aunt deletes it, file a lawsuit claiming censorship.

I don't want "my aunt" to be running a knitting pattern discussion website! I want "my aunt" to only be publishing/hosting what she herself writes, while her discussion partners each publish/host what they themselves write. I then want all of these messages stitched together to form a cohesive presentation on each person's computer, by software that represents their interests.

There was the better part of the decade after the CDA passed that the tech community was still focused on protocols that worked this way. Section 230 immunity made sites that centralized user content feasible rather than legally radioactive. Centralized sites then took off because they were easier to develop, and investment-wise they caused Metcalfe's law power to accrue to the entity running the site rather than to an abstract protocol.

I do agree that in the current context, there is a strong path dependence here - neutering section 230 would not rewind the clock. And the present political push is from a movement that wants to censor speech even harder than corpos already currently do. I'm talking about what could have been.
