I am not sure I agree with these companies being an integral part of society. I feel pretty confident they could be replaced by alternatives operated by other people and most if not all users would not notice the difference. But I've seen that happen with the early WWW with Altavista, Yahoo, etc.
And if they are an integral part of society then I think they should be heavily regulated for things like foreign and domestic propaganda and the promotion of dangerous falsehoods. It's either self-regulation (within legal reason) and whatever they decide is appropriate for their platforms, or they should be heavily regulated with guaranteed free expression as allowed by law.
How proper internet service is still held hostage by the likes of Comcast and Verizon is beyond me, with little discussion given while everyone talks about the leverage of these three companies.
The answer is yes but irrelevant as so are embezzlers, serial killers or would a hypothetical few who literally want to actively to destroy every trace of it.
The question is vague enough that literal cancer could get both yes and no as answers logically (cases caused by society part of it vs existing independently in species without anything to remotely qualify as a society).
