Not "like life threatening" - Bad for our society.
In that free public conversation is centrally crucial to the sanity of our society.
And having that public conversation controlled by a profit-seeking entity is definitely detrimental to that conversation. And thus detrimental to the sanity of our society.
And an insane society is obviously all kinds of threatening.
Again, Google is not stopping you from using your speech.
If they ban you, they are telling you that they don't want you on their private property.
They don't take away your internet connection.
When did society need Google, or Twitter, or FB to function? They do not. Those are simply three websites. There are literally millions more.
If this site banned me, I lost literally nothing. If Google Drive banned me(assuming I have an account, which I do not) I lost literally nothing. Same for FB. Same for Twitter.
