Then it sounds like LGPL is exactly what you want. That forbids people
closing your code, but allows linking of it to closed apps. Cf Tom's
comments, it's quite difficult for anyone to release code that depends
on GPL'd code without incurring the terms of the GPL for their code (and
that is clearly the way the FSF want it to be).

But as Joshua was implying, a common business model is to release some
code under GPL, which means it can be used only for GPL'd apps, and then
also be willing to sell other sorts of licences for it to be used with
commercial apps. If that's the sort of business model you have in mind,
then GPL is probably what you want.
