I don't agree with people who think these scandals will be the end of Facebook. Instead, Facebook will become more entrenched as it develops advanced features to handle national security issues, allow users more sophisticated control over their data, etc. I like that Zuckerburg explicitly takes personal responsibility for everything that happens on his platform in this post.
I realize you're not the poster I was responding to, but one has to pick one. Either this is a nullop statement, or it is an encouraging, commendable thing to say.
