Getting back to the OP, ---
I think that new tech may be testing the original concept of freedom of speech in the US.
My point is that new tech allows the spread of dumb ideas that people want to believe. If they want to believe it enough, they will believe it and spread it further.
AND, (as of now) there is never, and can never be, any legal consequences for this.
Take for example, that reported fact that EXON around 1980 drafted an internal memo that showed that CO2 being added to the air would cause enough global warming that around 2020 there would be serious climate disasters. The officers of EXON hid the memo for decades, and instead began a program to spread disinformation that would undermine the credibility of others who came to the same conclusions. IF this summary of the facts is true, then IMHO, EXON should be held accountable for this. It knowingly spent millions to cause the current climate change crisis. The scale of the damage so far suffered by the people who live in the forests of Calif. and Aust. is enough to bankrupt EXON, if it had to pay for those damages.
[Begin snark]I propose that we copy the anti-abortion law recently passed in Texas, and have some state (State-S) pass a law that any adult human person anywhere on earth be allowed to sue in State-S's court system for a minimum of $100K of damages the corp. of EXON (or any such corp. or person). And EXON must in any case pay the legal bills of both parties to the suit, as well as reimburse State-S for its court costs on a week by week basis. The plaintiff will win if on discovery it is found the EXON or any corp. spent $1M or more to create and/or spread disinformation that turns out to have caused $200M or more of damage in total to the people of the earth.
This law will scare others from doing what EXON did going forward.
Actually, the US needs to do some such thing to hold accountable the major spreaders of disinformation for profit that can be shown to have been knowingly created and/or spread false disinformation to protect profits (or maintain power) and that they knew was false. The statute of limitations would be 50 years to give the world time to realize what was done and that it was, in fact, false information.
