People often do not realize what "full access" means. They do not realize the value of personal data either. They desparately want to play the game though. That is very common. I often get offers for some "free" things I would have had to pay for them with personal data. So far I declined those offers.
Some of the people I know get even angry when they learn that the email address they received from me is "throw away" and actually gets thrown away after security breaches they consinder minor (e. g. spam or malware mails or mail from people they gave it to). They get even more angry, when they learn that it was the only email address they´ll ever get from me.
I have even seen software developers give away login info. They should really know better.
