To be perfectly pedantic, the history lesson ends in 1991 and the CDA was passed in 1996.
Also, I am not sure that this author really understands where things stand anymore. He calls the 3rd circuit TikTok ruling "batshit insane" and "deliberately ignores precedent". Well, it is entirely possible (likely even?) that it will get overruled. But that ruling is based on a Supreme Court ruling earlier this year (Moody vs. NetChoice). Throw your precedence out the window, the Supreme Court just changed things (or maybe we will find out that they didn't really mean it like that).
The First Amendment protects you from the consequences of your own speech (with something like 17 categories of exceptions).
Section 230 protects you from the consequences of publishing someone else's speech.
Where we are right now is deciding if the algorithm is pumping out your speech or it is pumping out someone else's speech. And the 3rd circuit TikTok ruling spends paragraphs discussing this. You can read it for yourself and decide if it makes sense.
