I've just put online a transcript of one of RMS's general free software talks: http://fsfeurope.org/documents/rms-fs-2006-03-09.en.html

AFAIK, the last time someone made a transcript of one of his general talks was in 1986: http://www.gnu.org/philosophy/stallman-kth.html

I think his 2006 talk is pretty interesting, but the comparison with a twenty year gap is also interesting.
