wait: CC licenses expire after you die, right, so your work is just in the public domain? or do the stipulations of CC licenses persist after death? (if so, when do those expire? ever?)

this seems like it should be both obvious and an easy thing to nail down, but I'm having trouble finding any good discussion of the question... is there a #librarian here who could enlighten me?

@mrgah That's a good question. Does copyright law take over where copyleft ends? I don't see any explicit mention of death in CC, so does the work become public domain 70 years after the author's death as with traditional copyright?

@annika

CC themselves do say that CC licenses are a way to grant permissions under copyright: "Our tools give everyone from individual creators to large companies and institutions a simple, standardized way to grant copyright permissions to their creative work."

from what @dredmorbius was saying, it sounds like the heirs to someone who's released something under a CC license can then change the license (and maybe even revoke the CC license for future copies)

that seems... weird
