Copyleft terms may become unenforceable in 11 countries due to the CPTPP
The relevant text from the linked pdf[1]:<p><i>>Article 14.17: Source Code<p>>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.<p>>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.<p>>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;</i><p>To point (1), the text seems like something Steve Ballmer would write to because "GPL is a cancer".<p>To point (2), I wonder if "GNU gcc" is considered "mass-market" or "infrastructure".<p>To point (3), I assume that proprietary software users will want the most narrow definition of <i>"commercially negotiated contracts"</i>.  This means reading the LICENSE.TXT that states "copyleft" and downloading from github is definitely not a "contract".   Therefore, copyleft would be null & void.<p>[1] <a href="http://dfat.gov.au/trade/agreements/not-yet-in-force/tpp-11/official-documents/Documents/14-electronic-commerce.pdf" rel="nofollow">http://dfat.gov.au/trade/agreements/not-yet-in-force/tpp-11/...</a>
