I'd cheer for a company like this.
It seems to dance just on the other side of what's legal, though.
Then I don't think you've thought it through.
This entire software ecosystem depends on volunteering and cooperation. It demands respect of the people doing the work. Adhering to their licensing terms is the payment they demand for the work they do.
If you steal their social currency, they may just walk away for good, and nobody will pick up the slack for you. And if you're a whole society of greedy little thieves, the future of software will be everyone preciously guarding and hiding their changes to the last open versions of software from some decades ago.
You should read Bruce Perens' testimony in the Jacobsen v. Katzer case that explained all this (and determined that licensing terms are enforceable, and you can't just say "his is open mine is open what's the difference?")
