I installed today the Kreactive Calculator from the Android Market and I realized that it uses my Arity library. As I released Arity under the Apache 2.0 License (a very permissive license), a new user of the library is usually good news. But Kreactive does not seem to be a good open-source citizen: they repackaged Arity under their own package “com.kreactive.arithmatic” instead of the original “org.javia.arity”, and they don’t acknowledge anywhere their use of the library. Basically it looks as if they imply it is their own code. Given Arity’s Apache 2.0 license, they really didn’t have to do this ’stealing’ — but I’ll take it as a compliment.

Anyway, good luck Kreactive with your Android apps, and don’t forget to be a good citizen next time!
