Clarifying tone on international copyright law (users be free)

[Dr. Maxie Dion Schmidt]

Reproduced from this emsec#218 issue:

I also want to clarify tone respectfully to any users who get the wrong impression about my attitude to adding headers to my DESFire source code:

What I added to the DESFire firmware source headers does not restrict individual users, even when they use their own compiled versions in commercial applications or work-related settings. What it does is restrict most vendors from redistribution of source or derivative work binaries en masse, e.g., limitations on shipping derivative works flashed on their devices to merchants or to use these sources in merchant linked firmware sources without express written consent.
