Well he put his email in a not so easily readable format in there, so someone has to take effort and invest time to generate a correct email address from it. With this time investment getting to the email address costs money. So not for free ;) But of course now we are definitely nitpicking on a philosophical level. My point basically if someone says something is free, but requests your personal data in return, then that is not free.
