I'm curious what your response to the Cambridge Analytica stuff was? Open APIs to build your own experience are like 100 times worse than that, at least the APIs that CA used were limited (such that they didn't provide enough info to actually recreate FB) and required CA to sign a developer agreement with FB to restrict how they could be used.

But then how would they force us to look at ads? How would they keep all their valuable data locked in their walled garden? Sadly I don’t think we’re ever going back to the glory days of open APIs.
