I do not know lol.
Just something I read on the internet, so it must be true, right?
But I think it means that once censoring starts, the censoring entity becomes responsible for *all* allowed content and can be sued for both what’s permitted and what’s censored.
But not a lawyer so not really sure.
The rule for a communications carrier is that they have nothing to do with the content of their messages delivered.
For example, if a surgeon is talking his colleagues through a difficult operation via a phone call (far-fetched, I know) and the phone call is disconnected, causing the patient to die ... there is no liability on the part of the phone company.
Likewise, a phone company is not liable for crimes that are carried out or pornography transmitted through their network.
This is the line FB and TWTR have apparently crossed, when the got involved in policing the content of their platforms.
Of course, they have to get involved in the “Content” if they are going to make money off of it.
So these are uncharted waters.
