And if I personally release some code under GPL, what then? Have I 
singlehandedly voided their patents, to which I didn't have any right in the 
first place?

I'd like to know precisely why IBM and Apple lawyers think that. I can't see 
it myself. Of course, I'm not a lawyer, but I'd expect to understand if I saw 
the explanation. Can you see an actual flaw in my logic?
