Before Trump, the "traditional" social media was likely pushing the Democrats' agenda (like the Twitter files under the guise of more moderation. Now the tactic is being used by the Trump administration just more in the open and in more traditional media (Jimmy Kimmel). Big media is such an easy target for govt influence when it's all ad supported.

I'd bet they see the writing on the wall that the government has too much influence in social media. So this time they don't want to be caught with their pants down when Democrats come back into power. The other thing I feel is on the horizon is the end of the ad supported internet. I've said it before, be prepared to do it yourself or pay for it. I guarantee the guys behind this instance is in the do it yourself camp.

Disclaimer: I am libertarian and view both DNC and GOP as different sides of the same authoritarian coin. Right wing flavored, left wing flavored, both are disgusting when it's authoritarianism.
