I think a better take is:
> Do you use personal / behavioral data / usage to shape the user experience and recommendations? You do not get covered by Section 230.
If they get to exercise editorial powers, then it doesn't make sense for them to be protected from liability for choosing what to publish. If they just give you a giant firehose, then they're not doing anything editorially and they should not have any liability as clearly that's not _their_ speech.
This - one hundred times this.
No matter what the “algorithm” is, at some point it’s a choice of what to put in front of the user - a publishing choice.
Unless the rules are solely determined by myself and deterministic (no selection or choice on the platform end) then they are publishers.
And liable.
