Right to speech doesn't mean write to publish that speech on any platform or outlet. Twitter, like a newspaper, also has freedom of speech to counterbalance your own.

High level officials employed by the US government criminally conspired against the United States to work with a private company and deprive US citizens of their right to freedom of speech for political gain.

Members of the FBI abused their position as law enforcement to collude with a political campaign and censor social media against damning information for their preferred candidate.

This is all fact.

This is not fact.

This is a narrative for people with no domain experience, and a desire to see conspiracies.

Right to free speech doesn’t govern private platforms aka Twitter

When government employees take government money (salary) to coerce and deprive citizens of their government-assured constitutional rights that is fraud.

The employee has committed fraud against the United States of America.

It's not a private platform anymore when it colludes with government.

Bingo. Twitter acted as a quasi-governmental entity. Its former officers are all personally liable.
