To say someone "opens up" implies the person has been closed off about a thing we had wanted to know about, and maybe felt we had a right to know about. Had Richard Nixon had "opened up" about the Watergate break-in in 1972, he might not have had to resign in 1974. Similarly, we're right to encourage our daughter to "open up" about why she has been in a bad mood since she got home from school.
Pretty much everything in between involves someone prominent being badgered into talking about something they shouldn't, or some fool celebrity blurting out some private stuff in order to get atten—I mean, "raise awareness," about the perils of some first-world problem.
Don't take the click bate.
