The reason for censorship by social media, which is their right because they are private companies, is that certain "Hate" groups were using social media to spread their message as well as to organize events like the storming of the capitol and the charlottesville event that the woman was killed by the lunatic in the car. In addition, people are using it to spread misinformation not to mention absolute lies that can incite violence or at least sway public opinion. The fact that they are private companies means they are into making money. If they don't ban these hate groups, hate speech, misinformation, and down right lies then the other 90% of their customers who don't approve of it will start pulling out. They also could possibly be held liable if their platform is used to encourage criminal behavior. They are gambling that censorship will save them the most money in the long run. I am sure the billion dollar companies have actuaries working on it right now to determine how far they need to go with it.
I've seen more than a few outright lies from the other side not be banned or censored.
