RMS doesn't have a problem with the ACL code (obviously he would prefer the GPL for it, but I reckon he would consider it free software), as he doesn't have a problem with GNU/Linux distributions shipping e.g. BSD-licensed code. And, yes, he is opposed to non-free books, though he distinguishes between those which should be modifiable and those which shouldn't be; for more on this: http://www.gnu.org/philosophy/copyright-and-globalization.html#opinions http://www.gnu.org/philosophy/copyright-and-globalization.ht... On a different note: there's is no reason to call him names for not signing ACL, he just takes a principled stand. Why should he sign it anyway? If I had a copy of ACL (yes, I am poor) I wouldn't want anybody but pg to sign it.
