There is a strong argument these adversaries have built domestic terrorist cells who have been running around in gangs threatening people, razing buildings, and engaging in nonsensical political discussions about disposing with government services, and they are using a social media company owned by a foreign state with stated military objectives to organize. Whether you want to view Antifa or Trump supporters as the terrorists, or TikTok, Twitter or Facebook as domesitic or foreign companies is a matter of perspective.
The fact is weapons of psychologcial warfare do not differentiate between targets and may yet proove to be as deadly as any WMD.
The reason Section 230 is under attack by the current regime is that astroturfing exercises on boards like this one to force perspective change and create sounding boards for corporate political policies has become a well documented business model as the recent deposition of FB and Twitter's CEO infront of congress showed.
The real insanity is that any CEO would ever think messing with people's brain chemistry without knowing what you are doing in order to make a buck was ever a good idea.
E2E solves none of the above.
