I see this as a key problem of our times. Social convention used to have a stronger impact on behavior. Now it isn't enough for behavior to be disdained, it must be flagrantly illegal.
Growth by any means necessary.. seems like there are a tens of thousands of apps that each act like their own data bureau, totalling dossiers on billions of people, just because it makes money. Maybe a few percentage points' value lost as a slap on the wrist every now and then. I feel, that in this scenario, rather than a better carrot, we need a better stick..
Social convention has always had a strong impact. Where I live, people will cut you in line if you leave a space big enough for them to fit and it's perfectly ok. Where I'm from, if someone did that, you'd end up with an angry mob and probably a fist in your face.
Social conventions are always stronger than the law; at least in person.
