Well of course the reverse is not necessarily true. !A => B does not imply A => !B . However I do not think there is any valid business model out there that gives something away for free, without making money off the people that get the freebies. Essentially even in a freemium model, free users are the product as they are marketing leads. Accepting that your users are the product does not necessarily mean you should be a jerk to them though.
