'View As' Could be an intentional feature
That feature could've been intentional for TLA's so agents can access anybody's private account, even if said agents were deployed overseas.
If not for TLA's and secret agencies, then maybe that feature was given to big corps who wanted some private data of FB users.
Just patched by FB when that Taiwanese guy claimed he would delete the FB account of Zuckerberg in a live stream.
That's why it's not good to put backdoors, as claimed by most tech gurus, be it hardware or software because sooner or later someone will discover those backdoors. Ok, as usual, just claim it was a bug and not an intentional feature.
