They essentially asked whether it would enable users to have privacy and would make it harder for the government to monitor every personal and financial moves of people in the US and around the world.
haha, not a chance.
as an information gathering source, Facebook is not going to add any sort of privacy to their token. it will be exact same as their platform, Paypal and any other centralized service void of any privacy.
specially when you consider the fact that Facebook is a company in US you can see that there is no chance in hell they are going to add any shred of privacy to their token. they want to gather more information and sell it to the 3 letter agencies.
