Generational differences
I don't know for certain that Millennials are more or less concerned with privacy than their elders, although from those numbers, I suspect that they're more concerned. But it does look like they may be differently concerned about it. At least, they seem to be concerned with keeping different things private.
All it takes is for a few practitioners of the ancient art of "if-it-bleeds,-it-leads" finding and propagating stories about "sexting" and the like and suddenly all of the young'uns are complete idiots in the minds of their elders. (It's not like we've never seen the biases of the "reporters" or their bosses reflected in what gets reported or how, is it?
Mind you, there are some out there who are plain stupid and just don't get it. (It has always been so. Don't tell me that none of your peers were "too stupid to live", however old you now are.) IMHO, kids who brag about having committed crimes on social media and especially those who post videos of their crime sprees should be sterilized in addition to whatever other punishment is meted out. They are, if not too stupid to live, at least too stupid to be allowed to breed.
