It would seem to me that any system that has more than 10% market share ought to be forced to carry all traffic. We can quibble as to the proper percentage, but when you have millions of users, you are a big player.
Social media sites all have Terms of Service.
Don't care. Terms of service which violate law should be regarded as null and void. We just need to pass a law requiring them to carry traffic, or don't serve the public.
Lots of conservatives are going to reject "there oughta be a law against that", but that is where we are.
Communists have all the big money. Communists control all the corporate BODs and executive suites. Communists control all the big tech outfits. Communists control all the banking. Commies control all the Human Resources departments. Commies control all the colleges and universities.
Currently, conservatives have a small majority politically. That is the only advantage we have, and that can go away as soon as next Tuesday.
We can push for regulation to ensure our survival. Or we can continue to watch the screws tighten until we die or start fighting for real.
