Problem is that too many people are getting most of their information from a single shared source (or small set of shared sources) which is controlled by relatively small set of individuals. This leads to small amount of people controlling the news feed for the majority, which is kind of an issue in democracy. For this particular case we have in hand antitrust policies and forcefully breaking Google and Facebook might be the solution. Same kind of issue however could rise even if there was no money or corporations involved at all. Think for example somebody suddenly purchasing Facebook, removing all ads and just running it as free social media site. The users would be still there and owner of the site controlling what they see. To tackle the problem we should get more creative. One thing that comes to mind is progressive tax on user base (or based on number of people you reach). Making in financially unfeasible to create a platform that covers too large part of the population. I'll skip thinking about the practical problems in implementing this. Ideal decentralized Internet solves this problem as we tear down the walled gardens. But what if people are too happy with the walled gardens. What if we just end up with another information monopoly - this time running in the decentralized network and outside the intervening hands of any government.
