Educators, and all those who wish to contribute to on-line educational works: please do not to let your work be made non-free. Offer your assistance and text to educational works that carry free/libre licenses, preferably copyleft licenses so that all versions of the work must respect teachers’ and students’ freedom. Then invite educational activities to use and redistribute these works on that freedom-respecting basis, if they will. Together we can make education a domain of freedom.
Mostly people don’t bother about what they get for gratis on the Internet, but institutions cannot adopt the same approach. Licensing is as much important as much as the actual content. But an archaic system will not go down till it is compelled to, and it will fight till the very end.
