I just noticed that the Android SDK is now non-free software. If you go to
and click on one of the files, you are presented with lengthy “Terms and Conditions” which for example say:
In order to use the SDK, you must first agree to this License Agreement. You may not use the SDK if you do not accept this License Agreement.
This sentence alone already violates freedom 0, the freedom to use the program for any purpose without restrictions.
Today, the truly Free Software version of Android called Replicant came to the rescue and released a free (as in free speech) version of the SDK.
