Earlier quoted context omitted.
It's one thing to enjoy benefit of doubt, it's another to just make up utterly unbelievable fringe crap that can be explained by hundreds of other explanations.
Snowden revealed a lot of stuff that was the just domain of crazy fringe theories before. Anyone morally okay with facebook's known problems would also most likely be morally okay with spying on users like this. Hence, I agree that giving them the benefit of the doubt is irrational.
Look back at everything he revealed
That's LITERALLY conspiracy Theory proven to be conspiracy reality
And that guy, Keith Alexander, is now on the board of Amazon
so giving large tech companies like Google, Amazon, FB the benefit of the doubt is insanity
