hmnn....the problem here is that these privately owned companies may do what they wish to do according to their own beliefs. It would be VERY wrong to stop them. On the other hand, they also seem to have the power to stop conservative thought and expression. I was very personally affected by this last year, when I was actually kicked off a knitting site for my less than extreme political views. I was not only kicked off, I was threatened, insulted, and stalked. It was pretty miserable there for quite a few months...because I was NOT a slavering left wing ***** hat wearer. I wasn't a dyed in the wool Trump supporter, either, but that didn't matter to anybody. I was a target because I wasn't extreme left wing.
So these people have power...real power...to destroy lives, and they do. They not only allow it, they encourage it. I find that to be problematic. What there should be is equally powerful sources of information from the 'other side,' and there seems to be a dearth of that. Look at what criticism of Fox News is out there. Nobody can say that Fox News is as powerful or influential as Facebook or Instagram or whoever, but for some reason, Fox News is considered to be anathema, where Facebook and YouTube are not. Any percieved bias by Fox is condemned to the maximum...and all such discriminatory censorship by the other guys is defended. I don't want the government messing with private opinions, no matter how big that private opinion is.....but that's a very conservative thought that buys right into liberal thinking, which seems to be that their way is the right way and any differing though should be legally prohibited.
We can't win.
By the way, I have read 1984, and today, if one is a conservative, it looks very much like that. Newspeak indeed.It is very frightening, frankly.
