The traditional answer has been copyright-based licenses such as the General Public License, a legendary legal hack on copyright law that ensures the perpetual “shareability” of all licensed code. The GPL requires that third parties make any derivative software programs freely available to everyone and that they use the same license, thus ensuring that all future downstream uses of the code will also remain shareable.
