To be honest, #3 is a very broad generalization. It wasn't Silicon Valley that gave it up, it was Reddit, Google, Twitter, and FB. The problem is, public perception of "tech" is largely driven by those three companies as they are all handling the largest collections of social media. The truth is, the powerful have come to realize "free speech" being protected was only a safe position for them when people were unable to organize en mass without serious sacrifices. Now that they have, they feel a need to make it stop. It is the same reason they killed Unions and tried to kill Protesting. Both are threats to those in power. Online organizational ability is another threat and they are testing the waters on punishing people there as well. They can't stop it, just reduce it.
