Obviously stealing the App is bad idea, and should be condemed, however you must realize that some parts of the new Apps contain (and always will) some parts of code, examples, samples etc from other Apps. The problem is not in the fact that someone's App stollen, but in the fact that there are people like this doing it. The universal law says that there are always be a thieve and the victim. It also say, the more attention you put toward the problem the more of that problem is attracted (and if you disagree, then I recommend you to watch THE SECRET).
I agree with the idea of putting official disclaimer in the example App (that the code is only for educational purposes, and cannot be used to make money). I also like the idea of embeeding some kind of logo or warning in the compiled APK, but everything else would work against the product. Example Apps, and pieces of code ia a MUST for the users community to grow. If I need to spend hours to search for something or exchanging tons of messages with the developers asking for some kind of permissions, or begging for code I would rather give up and go for some other tool.In cases like this Erel should follow careful verification and take action if necessary, but in my opinion every App is (up to some extent) a copy of another App.
Despite cases like this one I still hope for more and more examples coming.
