This just occurred to me while SCO's most recent attacks upon the GPL
as a tool for destroying proprietory software: As we all know by now,
Microsoft are the puppeteer, ing Darl and his paid mouths around
the stage to spout their gibberish. Yet, Microsoft themselves have
been instrumental in destroying countless (non Microsoft) proprietory
software companies when it suits them.
So, in effect, the chief culprit is the one complaining about the GPL
managing to destroy its cometition legally, when MS have to resort to
illegal means to do so ;-)
It was also interesting reading the SEC filings ...
