Sorry, but this is a huge reach. Former government employees are not lifelong secret agents any more than Franz von Holzhausen is secretly working within Tesla on behalf of former employers VW, GM or Mazda.
If you've spent time in Silicon Valley you know there's no shortage of high tech employees eager to combat Covid misinformation and election lies. They don't need help from "Big Government" to go overboard. And despite Elon's promises of transparency and bombshells, the cherry-picked "Twitter Files" excerpts have shown none of the government censorship or First Amendment violations he claims. For example, Matt Taibbi himself said:
Twitter went way beyond "not amplifying". They fully suppressed the Hunter Biden laptop story mentioned above, and even locked the NY Post out of Twitter for a while over it. And much the same with Covid, election lies, etc. The question is whether they were following orders from the government.
And even if Twitter acted on its own, as all evidence indicates, it raises Section 230 issues. Fox and MSNBC are 100% free to ignore and/or slant stories. It's not illegal, even when done on behalf of government (e.g. President Trump calling directly into Fox). But social media companies supposedly provide a "town square" and do not exercise editorial control. Supposedly.
Not under Section 230.
