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.
It goes onto to exempt demanding copies of the source in commercially negotiated contracts, quality assurance, patents, orders made by judicial authorities or to comply with the regulation. The one notable exception to the exemptions: copy left licences.
The sky is falling, the sky is falling!
What is now proved was once only imagin'd. -- William Blake
