The Big Tech oligarchs believe that they can and must silence those who do not agree with the Left in general, and with Democrats in particular. Therefore, they have purged many conservatives from Twitter, in particular the President of the United States, and from Facebook, most notably Brandon Straka's WalkAway Movement, which had 500,000 members.
Freedom of speech is enshrined in the First Amendment to the U.S. Constitution. Other than yelling "fire" in a crowded theater (and in a few other instances), the Supreme Court has ruled in numerous cases that free speech is free speech, whether you agree with it or not.
One of the things that we have learned is that we must not leave the power to communicate freely in the hands of leftists, who are acting like fascists. Conservatives (and just those who believe in freedom) must develop our own infrastructure, so that we can't be crushed by the leftists, which has happened to Parler. We must and will fight back. At this time, many people are going to Gab.com and CloutHub.com. We will not be silenced by the radical left. Period.
