What "big tech" is doing is not new it's the same game that companies have been doing since there have been companies. Common carrier status was always about not being party to messages of your users. Big tech is absolutely party to the messages of their users, even private ones. We all know it, they do it intentionally and even the stodgy old people on the supreme court can clearly see their game.
If you're going to "control the narrative" by choosing what people see and what the don't, then you need to be responsible for what is displayed. This isn't and opt-in level of control there's not even an opt-out. They blatantly decide what the news is and feed it to you, no matter what you try and do to search around it.
It has always blown my mind that google maps has no option to show all the points of interest no matter how far you zoom in. Just one tiny example of a service populated by users but then controlled by the machine.
Be a common carrier or don't be. This manipulation game needs to end. I don't know what the court will do but hopefully provide guidelines on what common carrier is.
