So now you've come to attacking me in the third person. I'll try again. I like the DFSG-4 fine. Indeed, it covers TeX, and crucially so, because tex.web permits modification only in the form of patches. Similarly, cmr10.mf permits modification only if you change its filename. Both of these are relatively harmless, in large part because they don't affect what we name commands or filenames in the installed system. Accordingly, DFSG-4 is a great thing! It correctly labels TeX (and, I see now, CM fonts) as free. But if we cannot install what we want on the system, when it comes to the functional elements of the programs (not what is displayed in banner messages, for example) then the software simply is not free. TeX actually *does* allow us to do this. And the LAPL just doesn't. The LAPL is, in fact, *different*. Not by some mysterious thing, but it's manifestly different. We can quote the terms! You have insisted that it's the same, by pretending that there are lots of extra conditions attached to the distribution of TeX. While many of those are things that any sane person would do, they are not, in themselves, licensing conditions on TeX. I'm quite sure that Knuth is very confused about the way licensing works. He has himself, in the same utterance, said that he wants something to be public domain, and that he wants its distribution or use restricted in some particular way. That is a manifest indication that he just doesn't understand free software licensing very well. Heck, many people don't. But the actual conditions that he has attached to his works, in the actual licenses, are not offensive to the DFSG. And the LAPL--which is *different* in its text, *different* in its requirements--does seem to. Thomas
