You’re totally missing the GP’s point. You’re also absolutely right that the social media content: the photos, the sentiments, the likes, the connections, should not in any way “belong” to FB/G. The data that does belong to them, and that is useless to anyone else, are the outputs from their sentiment analyzer service, the weights and trigger conditions for their content ranking algorithms, the intermediate outputs of their ML evaluations, etc. GP, and the article, are saying: look there first. Try to start by truly understanding “what you already know, but aren’t paying enough attention to,” and don’t just treat the problem as “needs more data.”
