Q
If the gov't censors protected speech it's a violation of the 1st A.
If the gov't pays a third party (Google, FB, Twitter) they're censoring by proxy, which should also be a 1st A violation.
Splitting these companies under monopoly rule probably won't work because people will move to the most popular, ie Myspace>FB.
The gov't has control of these three entities in multiple ways, which include:
1) Initial investment through IN-Q-TEL, etc.:
2) Payment by the gov't of $160M to combat fake news through HR5181:
3) State pensions investing in these funds and having input as activist investors:
4) Being directed by CIA employee: and
5) Other subsidies and contracts from the government I've overlooked.
