I know many devs are autistic with psychopathic tendencies. Who lie frequently due to the psychopathy but haven't tested in reality due to the autism to see if their lies are convincing enough. But one simply can't yell “I do it for privacy!” “Code is speech, and speech is free!” “Open source!” and expect people to buy your lies.
To see someone’s actual motivation you have to put it in the context of what they do not just what they say. The same principle applies to business as well. Whatever the creator claims they do it for is irrelevant. Assume governments are actually evil. Yes. You don't want them to see you. But any kind of business would require transparency from both sides. Unless both of them don't mind screwing the other over. Which is rare. Because if you plan to screw someone over, normally you don't want them to screw you first. Therefore you there is always at least one transparency from one party.
The question then becomes, what kind of people and what kind of business that would rather risk the possibility of not getting the money at all, over the possibility of being discovered?
