I'm wondering if now people like Zuckerberg, for communications like this, instead of email will be using something with auto-delete features to avoid get this messages on the internet in 10 years.
Do you think that on the time of writing he knows that this can be public someday?
This is public because some law force Facebook to give this messages to the government and they publish it? Some recipients leaked it? FB was hacked?
I get some negative feeling on reading this messages that seems to be written as private.
