>Article 14.17: Source Code
>1. No Party shall require the transfer of, or access to, source code of software owned by a person of another Party, as a condition for the import, distribution, sale or use of such software, or of products containing such software, in its territory.
>2. For the purposes of this Article, software subject to paragraph 1 is limited to mass-market software or products containing such software and does not include software used for critical infrastructure.
>3. Nothing in this Article shall preclude: (a) the inclusion or implementation of terms and conditions related to the provision of source code in commercially negotiated contracts;
To point (1), the text seems like something Steve Ballmer would write to because "GPL is a cancer".
To point (2), I wonder if "GNU gcc" is considered "mass-market" or "infrastructure".
To point (3), I assume that proprietary software users will want the most narrow definition of "commercially negotiated contracts". This means reading the LICENSE.TXT that states "copyleft" and downloading from github is definitely not a "contract". Therefore, copyleft would be null & void.
