I read and watched a bit on what is going on.

Currently, in America, several people are bringing forward different ideas on how to stop Google, Facebook, etc. from abusing their power and controlling what people can and cannot say on their social platforms. As it stands, they are posing both as a publisher and a public service which allows them to do this. They refuse to pick a side and the laws that are trying to be put in place will force them to choose.

If they decide to be a publisher, then anything anyone says on their platforms will be held against them if it is in the wrong.

If they decide to be a public service, they will have no say in what people say on their platforms nor be able to silence them but will not be liable for it.
