The government is never a passive actor. So non-intervention is also active policy. You can only choose what the policy is. The active policy for the last 15 years has been to consolidate a social media oligopoly with very few restrictions. Users are being tracked, advertisement laws are being skirted and are less restrictive than in other mediums, data is being sold, dark patterns are used to keep people from making their own choices. The algorithms are actively promoting bad content because the social media companies are not held liable for their part in promoting false content.
Depending on where you live it is not true that there are no restrictions on false advertising and accountability for commercial content.
That said, a government can be passive and not regulate a field and non-intervention stays non-intervention, be it conscious or not. But that is besides the point. A government that tries to regulate all aspects of life is usually connected to totalitarianism, an that isn't only a libertarian position.
