Re: possible readline license problem with ghc and -package util

:) The question here is, are you (plural) really trying to write Free Software or just giving something away now, which will be closed and hogged later?

The copyright holder(s) of a piece of software is free to change which license future copies are released under. It makes no difference whether the license is GPL, BSD, Artistic, Microsoft EULA, or whatever. (This is why the gcc team insist that all copyrights on gcc patches be signed over to the FSF.) In other words, the GPL gives no more protection against free software becoming non-free than the BSD license. The only defence against this is for the copyright owners to make a legally binding promise not to do so (as the FSF have done). -- Alastair Reid
