It is best to take the pessimistic view whenever it comes to how policies are applied and how technical solutions are used. Sure, it can be used constructively, but there will always be a few assholes using it to oppress their enemies and exploit it for material gain. Much like you can predict the success of a spam filter by thinking about how it will be exploited by the worst 1%, it is instructive to think about what this tool will do in the hands of ignorant, uncaring and corrupt assholes, because that's probably how it'll turn out.

And that's why we can't have nice things, which is the common thread between telemetry in win10, trigger warnings in colleges and censorship on social media.
