A friend just asked me a question about copyright and terms-and-conditions when using a product and it's quite interesting.
I have a website where I host software projects, and include a license with every release of my software. What happens, if say someone downloads my software, removes all my licenses, and reuploads it in their own domain. Sure, I can send them notices to remove it, but lets say someone downloads it from their site and then uses it in a commercial product, or in a way sanctioned by the license.
Does this third-person then suffer in some way as the source they obtain it from was illegal or do they immediately have to abide by the real terms and conditions if contacted by the owner of the software?
