To expand your metaphor: Facebook is a roped-off section at the edge of the public square. Most people who visit the public square spend most of their time in this roped-off Facebook section. In the Facebook section, Facebook concierges monitor each person carefully. The concierge will occasionally bring various third-parties up to each person while constantly gauging engagement as a proxy for how likely a person is to return to Facebook section. Facebook uses their engagement metric (plus all of the observations taken to derive the engagement) to value and sell access to (through the concierge) their patrons. You are equating some specific consequences of this concierge service to censorship as if that is the only problem. This censorship is not the only problem it is also not even a relevant problem.
