Seems like the “CPTPP” aka “TPP-11” (TPP minus the USA) may not be entirely free of objectionable provisions. A submission to the Australian ratification process <https://www.techdirt.com/articles/20180615/09090440050/open-source-industry-australia-says-zombie-tpp-could-destroy-free-software-licensing.shtml> has pointed out the following problematic clause: 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. As you may know, such an access requirement is an integral part of copyleft licences like the GPL. What this clause seems to be saying is that such a requirement is unenforceable under the TPP.
