I may be naive in this, but aren't most people not assholes? Including free users. I would guess that most free users are nice enough and would appreciate the work you do. Also, making a product free is nice because if it is really cool, users will advertise for you. If I love a product I will share it. Simple.

Maybe OP is jaded because a couple of bad free users trashed his work.
