My objections are thus: 1) Facebook uses any info I put into their platform to create a centralized, indexed, searchable, public database of people. This is dangerous for a lot of reasons, but notably in the vagaries of Facebook’s privacy settings (which seem to get reset every so often). 2) Facebook allows advertisers to target using a huge number of selection criteria. This allows advertisers to target some very specific — and vulnerable — groups in a way that is creepy at best. See also how the GOP was easily able to target specific racial cohorts in tight districts to spread FUD — the same tactics also work outside of politics when trying to sell things. 3) Machine learning outside of Facebook’s control makes it trivial to connect social media accounts to other activity the user may perform on the Internet — and thus connect that semi-anonymous online content to their real world relationships (e.g. the database of porn actresses linked to their Facebook profiles) This collection of user data is Facebook’s entire business. The whole corporate bureaucracy is set up to protect this database and its data collection activities. You can’t have Facebook without it. So in a word, a lot of people object to Facebook’s entire business model — it’s just most people weren’t aware what that model asked them to give up until recently.
