I was with him until he got here:
"Censorship in America is running rampant over citizens' rights defined under the First Amendment," said Executive Director Patrick Wood, "big tech companies like Google, Facebook, Youtube and Twitter are actively suppressing all other viewpoints except their own narrow interpretation of what society ought to be."
The first amendment protects against government censorship and sanctions against free speech, not against corporate censorship or sanction. That said I like that their solution is to create their own non-censored platform, that's the right solution to combat corporate censorship.
Your point is well taken, but the lines of demarcation between government and Big Tech are blurred. Both sides are deep inside each other's pocket. In one sense, this blending resembles a Public-Private Partnership.
What I would say to argue this is that such companies have grown to the size where they are now essentially public accommodations and should then be regulated as such and prevented from discriminating against people based on political affiliation or speech. Google is essentially Woolworth's lunch counter. But remember that they actually voluntarily desegregated their lunch counter prior to being forced to by legislation due to public pressure and publicity.
