drafts of GPLv3\S3\P1 referred directly to the DMCA, but the final version

instead includes instead an international legal reference to

anticircumvention laws enacted pursuant to the 1996 WIPO treaty and any

similar laws.  Lawyers outside the USA worried that a USA statutory reference

could be read as indicating a choice for application of USA law to the

license as a whole.  While the FSF did not necessarily agree with that view,

the FSF decided anyway to refer to the WIPO treaty rather than DMCA, since

several national anticircumvention laws were (or will likely be) structured

more similarly to the anticircumvention provisions of the DMCA in their

implementation of WIPO\@.  Furthermore, the addition of ``or similar laws''

provides an appropriate catch-all.

power to forbid circumvention of technological measures only to the extent

that such circumvention is accomplished through the exercise of GPL rights in

the conveyed work.  GPLv3\S3\P2 makes clear that the referenced ``legal

rights'' are specifically rights arising under anticircumvention law.  and

refers to both the conveying party's rights and to third party rights, as in

some cases the conveying party will also be the party legally empowered to

enforce or invoke rights arising under anticircumvention law.

These disclaimers by each licensor of any intention to use GPL'd software to

stringently control access to other copyrighted works should effectively

prevent any private or public parties from invoking DMCA-like laws against

users who escape technical restriction measures implemented by GPL'd
