Two factors play into this publicity of private individual lives.

If everyone's skeletons are out in the open for everyone else to see, they're no longer skeletons.

What one social group considers a skeleton in their closet, another considers a badge of honor.

I benefitted from this, I'm into and have been into all sorts of things that would have socially stigmatized me 50 years ago. Meanwhile, someone else who is racist or beats their spouse or kids is likely to face social condemnation.

Times change, in this case, for the better.
