This is currently a matter of legal debate, but I don't think platforms can be held accountable for (most of) the actions of their users. A large part of what would be considered "destroying the fabric of society" - fake news, vitriol, intellectual sophistry, racism, sexism, hatred, etc. - predates Facebook. People have been nasty to each other since time immemorial - a better interpretation is that online dialogue, once the rarefied purview of a select group of well-educated academics and students, has caught up to offline dialogue, rather than deteriorated it. Algorithmic feed curation has added an element of insularity, but people have always formed communities around what they think and care about. Failures to educate, to inculcate critical thinking, to distinguish between truth and falsehood - these are not the shortcomings of social media not its responsibility to fix, but rather the fault of broader educational and corporate systems that prioritized vocational knowledge over inquiry and examination. We brought our own cudgels - social media is simply another area to bludgeon each other to death. Facebook can and should be held responsible only insofar as it has directly and with intent manipulated information - I don't think this has happened so far. Attempts to try and make Facebook fix what other systems were supposed to do are examples of first-order thinking - it's more effective to improve schools and colleges, offer opportunities for socioeconomic mobility, and reduce costs of living so that people can be healthier, smarter and more capable, so that they are less likely to begrudge offline or online.
