>You don't have a right to Twitter.

Regulation over communication channels is not only common through the ages, but expected and needed. There may not be literal landlines to worry about in the modern age, but the general idea of communication being an important medium that shouldn't be squandered by competition remains.

I prefer everyone to simply leave Twitter and to let it crash and burn, but I see the arguments to have stronger regulations on channels central enough for governmental entities to be using it as a communication hub.

This pattern is exceedingly common:

Multiple government agencies have a gap in capability. Larger government body chooses to leverage a popular (private) company Z solution over trying to develop an internal system. This is often because it's already been done in smaller jurisdictions. Z becomes head of agency/regulatory capture cartel. Z abuses the position to curtail the government actions/enable further corruption/abuse.
