Blatant self-promotion on my part, but I don’t see this argument made often enough.

TL;DR
  • “No derivatives” licensing does not protect against things we want it to protect against (either because these are explicitly allowed for by the copyright law, or because the copyright law already disallows them);
  • and at the same time stops people from doing things we might consider interesting or beneficial;
  • while making it harder to promote libre licensing and libre-licensed works.
