Personally, if you find something I write useful that I have made available (bearing in mind that the GPL doesn't make me give it to you in the first place) then good luck to you. I'd rather you didn't use it to misrepresent me, but it's a chance I'll take.
On the broader point, I think that software patents have become utterly devalued by, mostly, becoming an end in themselves. The phrase is hackneyed but nevertheless true - the only people who are benefiting are lawyers. I believe that there is a possible situation where patents could be granted for genuine work that actually involved some effort and research rather than some vague, broad concept. However, that isn't what's happened and I think no software patents at all is preferable to the farce we have at the moment. It's no benefit to anybody actually writing code.
