As I posted in the other thread... I think you'll find they have not broken any of the licensing rules attached to the "Open Source" bitaddress.org...

The permissions are quite explicit that anyone can basically to whatever they want with the source code... including sell copies of it... as long as the copyright and permissions notices are left intact... which it would appear they have done... and by removing the bitaddress.org branding, they ARE adhering to the license... as the name and logo are not part of the open source license so must be removed.
I'm fairly sure the Mnemonic checker is also under MIT license... and so is Coinb.in... can't say for the balance checker, can't seem to find any License for it...
While it may be pretty poor form to not be as forthright as perhaps they should be that the code is a derivative work... it still isn't some sort of huge crime.
