So this is my question: supposedly we can use the Apache License to include externally-written modules of code, within our applications. Yet, if I'm not mistaken, the License seems to state that we are required to include a copy of the Apache License when we distribute our code.
Then, when the recipients of our application notice the Apache license, what's to prevent them from thinking that our application is also falling within the Apache License, and hence they would also have permission to modify and distribute our application?
Do we have to augment the Apache License to simply state that it only applies to a portion of our code, and provide a link to the original modules that were used/copied/implemented-from-an-outside-source?
