I also completely understand how you posted a screed, without making a point at all or taking a side at all.
That Facebook has found a way to have a service that provides content, and not have to pay for it, is one of the reasons they are so immensely profitable.
I kind of laugh at your comparison to a warning in front of a show that its 'fictional' as some sort of equal warning and how that relates to what right wing cable tv news and radio have been putting on the air nearly 24/7 for the past 3 decades.
My point, is that the seeds of the misinformation and right wing propaganda isn't the leaf node that is facebook, but comes from the right wing media outlets, that are carried on cable or over the air. Its also a concern that no one on the 'left' seems entirely concerned about this, when you can dump on social media.
Your point seems to be that a cable company purchasing shows from content creator companies, is the same as facebook having random users post whatever they want. One of those is a broadcaster purposefully running content they want to run. The other is a platform to let anyone say whatever they want. When you give a platform to someone to say whatever they want, you are free to put limits on that platform, and warnings on that platform. When you are purchasing content, you are showing what you want to show. Things aren't "carried on cable or over the air." Things are bought by the broadcaster, then broadcast by the broadcaster.
I do believe you're being purposely dense here, so this conversation has now come to a conclusion. I won't read your reply.
