Same here. I mean i don't do this for a living either, but it still bites my @$$ when someone thinks they can just come and take it.
What really gets me is that people that make programs/sites like that think that there isn't any consequence for them deciding to get greedy and taking other peoples hard work.
I just hope they take down the site and prosecute whomever made it. (Unlikely though that may be.) :\
