i just noticed, that A4.1 should have another comma, for symmetry > + for any works, in publicly accessible repos.
as the definition of 'nonsharing' is not going to be obvious to people, this patch should have another iteration if 'nonsharing' is not synonymous with 'proprietary', then that term in A4.1, could be a hyper-link to its definition - i am not familiar with 'nonsharing', as a well-defined concept, or if it is defined elsewhere on the gnu.org website - my clone of www/ does not contain that term if 'nonsharing' is synonymous with 'proprietary', i suggest that the term: 'proprietary' would be much more obvious to people
