Think about it in terms of what is rational. If there were serious costs to having your data leaked out like this people would rationally have a bit more trepidation. On the other hand, we are in the era where everyone by now has probably been pwned a half dozen times or more, to no effect usually on your real life. You might get disgusted that instagram watches what you watch to serve you more of that stuff and keep you on longer, other people love that sort of content optimization, I literally hear them gloat how their social media content feeds at this point have been so perfectly honed to show them whatever hobbies or sports they are interested in. Take a picture and it pushes to 5 services and people love that. Having an app already pull your contacts for you and match them up to existing users is great in the eyes of most people.

You are right that on the one hand these things could be used for really bad purposes, but they are pretty benign. Now if you start going "well social media posts can influence elections," sure, but so can TV, newspapers, the radio, a banner hauled by a prop plane, whatever, not like anythings changed. If anything its a safer environment for combating a slip to fascism now vs in the mid century when there were like three channels on TV and a handful of radio programs carefully regulated by the FCC and that's all the free flow of info you have short of smuggling the printed word like its the 1400s.

Given all of this, I can't really blame people for accepting the game they didn't create for how it is and gleaming convenience from it. Take smartphones out of the equation, take the internet out, take out computers, and our present dystopia is still functionally the same.
