It is not only about violating licenses, rather leeching whatever software they feel like it, without give a cent back.

And there is no way to validate that.

i would assume they are not contributing but if i wanted to find out if they did, i'd ask them. should be fairly easy to validate if you know what they're contributing to.

while i agree with your point about this being sub-optimal for both software-development and free software as a whole, i think it is a separate issue.
