There are various licenses for source code to be licensed under. On the Stack Exchange network, Creative Common's cc-by-sa 3.0 is used. Does this really only apply to the source code? Does this mean an individual can copy the source code, possibly change it, compile it and distribute the object code or executable?
In other words, as long as the source code is not distributed, can anyone do anything they like with the compiled code that used the source code licensed under viral or restrictive licensing? I've never heard of a program itself being licensed under GPL or CC etc.?
