Do you believe freedom of speech applies to foreign governments?

So it was not limited to foreign government operations (or to QAnon, since it is phrased as a mere example).
People are ghost banned for poor language and insults. You have to imagine that Twitter is generally not very permissive based on how they treat average users. Many of the #NAFO folks are shadow banned.
This whole spectacle seems like a giant straw man in the making. The people that ran Twitter set it up based on their own belief of what is acceptable and there is nothing wrong with that.
