It is impersonal communication, addressed to an unseen mass rather than to a known individual, confirming statement 2.

It works through gatekeepers who decide what content passes to the public, upholding statement 3.

Statement 4 claims the feedback is ultrafast, but in mass communication feedback is delayed and indirect.
