I looked at half of them and found nothing about how much stuff people see on social media is this. One apparently had its content seen by 140 million Americans. So what does that mean from the point of view of an individual? Is it most of what they saw? 10%? 1%? 0.0? I have no idea and neither do you.

It's a popular misinformation technique of news companies to do this - planting a false idea in the heads of their enthusiastic audience using truthful information presented in a blustery way that leads people to believe something it doesn't actually say.
