Earlier quoted context omitted.
Why should “a service” silence anyone? How about letting people make their own decision who they want to talk to, without a third party saying “I forbid it”.
Can I use an analogy from biology to shed light on the valid point you have? Human beings exist as part of a society--a larger organism. Imagine if a cell were permitted to send any proteins or RNA it wanted to its neighboring cells. As long as the signals are benign or simply "nuisance" level, it's fine. But if the signals subvert the very organism of which they are a part--for example, by tricking neighboring cells…
In your own example you alluded to cells refusing to commit apoptosis. By your analogy, it should be just and proper for people to be regularly savrificed for their state — their very lives may be required to be given up for the state to function.
I do not think we base our human societies on the law of the jungle — and certainly not on the inner workings of an organism! I doubt you are able to take this analogy very far without coming up against horrendous human rights violations.
