Of course, data confidentiality should come first for any company. But what do we see in reality? Mobile operators sell databases, sometimes it seems that even banks spread information about the contact information of their users. If Facebook adapts cryptocurrency payments, it will only help its rating. There previously were much info that Facebook confidentiality = zero, everyone can buy user's password, what r we gonna see if they launch crypto payment?
Companies are all about profit, remember that. They will make money doing something they are not supposed to do,,, as long as they believe they do not get caught. Listen to Zuckerberg at the trial,,, he admits a few things and pretends he does not understand some things. He knows he talks to old people but acts so cocky. Even caught, he wants to be the good guy and make it look like he was not really doing anything wrong.
