I can see both sides of the argument here. On the one hand Amazon are just using open source literally as the license allows. But on the other hand it does feel a little underhanded that Amazon can incorporate these projects into their portfolio as their own and make large amounts of money from it while not giving anything back to the community. Maybe there needs to be a new software license. One that allows for commercial use when the project is included as a module or infrastructure but excludes it from being billed separately. So you can use an open source component as a language library, shared object / DLL or even stand alone daemon / service installed as part of your web application (for example) but you cannot make that open source project a product in its own right. Obviously a lawyer would need to write the terms rather than an engineer like myself but I wonder if that kind of software license would offer a happy middle ground?
