The thing that so many people fail to realize is that the data isn't valuable in and of itself. Excluding the type of information that lets you steal identities (and therefore bank accounts), there's not much you can do with huge swaths of data. There's not really a market for sheer information. What makes Facebook (and other platforms that use your personal data) valuable is that they have both information about you…
I relish seeing the day that Facebook is jettisoned for a system of distributed and individual ownership of profiles and data, like the internet should be. Humanity strayed at some point when the nefarious actors like Zuckerberg and his predecessors came in and started stealing your data, stealing your person, removing the information from you that your liberty and freedom is built on. You are not a free person when you are on the internet, your person is being smeared and skimmed everywhere you go and things against your choosing or even awareness are being done to your person and identity by people and for reasons you did not authorize. That's not liberty, that's not freedom.
