Facebook should have the freedom to remove any information they choose. They are not "censoring" it because that same information is available on thousands of other sources.
We do not need government telling Facebook what it can and cannot display on its site. Government cannot require you to express views you find objectionable--that is free speech.
If you don't think you can find sources that present false COVID information (YouTube), then you haven't looked. It is available-Facebook should not be forced to display it.
Thankfully, we have the 1st Amendment to protect that free speech from those who want government repression.
