Your attitude seems unnecessarily negative. Let me give you a theoretical example:
I live with my girlfriend. My girlfriend's birthday is next week and I want to plan a surprise party. I send a message out on this thing instead of Facebook or email (where she might see it).
When the vast majority of people talk about not leaving a paper trail, they (rightfully) aren't concerned with third parties -- they're concerned about second parties. Snapchat didn't take off because people were trying to hide from governments, it took off because they were trying to hide from friends and parents.
