I wrote most of this in response to OP's original post and never hit Post. I know its devorim peshutim, but since I wrote it already.....
My thoughts, mostly formulated after I was intimately involved in an incident several years ago where a news outlet violated the privacy of a grieving family moments after confirmation of death, before everyone was told, with a callous, "we have our poskim" answer:
1) The seforim talk about how people gravitate to fill an emotional void, and if its not filled with devarim shebekedusha it seeks out horror and other stimuli. Hence the attraction to horror movies, and car accidents.
2) People who profit off that, even if done k'das ukdin are no different than loan sharks with the right paperwork. Maybe muttar, but I'm glad I'm not in that line of business
3) We need to teach our kids tznius bechol inyanim, and ingrain deep within them a respect for other's privacy as well. And that is the only hope.
4) and surely, we should not be the ones forwarding or sharing other's texts or whatsapp's, without express permission, as is explicit in halacha
