That's not how laws work. At all. Even the GPLv3 (authored by one of the biggest activists against software patents) has clauses relating to software patents -- because they are a legitimate threat to software freedom and need to be addressed. Just because you don't like patents doesn't make the problem go away -- in fact by ignoring it you're making the problem worse because then your code's license has no protection for your users.

But a boycott is supposed to help the cause, no? All you're doing is preventing a lot of people from using your code from fear that you'll sue them - some of which who might end up using an alternative from a company that holds and supports patents.

That's not a boycott. That's a capitulation.
