I seem to be out of date. FSF doesn't, or at least didn't the last time

Why? Asking a contributor to sign a special agreement is saying that
you want them to grant *you* more rights than they are granting to
everyone else. If you license your stuff under the GPL without a dual
license, and I send you a patch also under the GPL, you have nothing to
complain about. If your business model depends on dual-licensing, you may
indeed want extra rights, which I may or may not be inclined to give you.

Again, I don't understand that.
Actually, I should have spoken not of fending off lawsuits but of
prosecuting them or threatening to do so, which is harder if there are
multiple copyright holders. The FSF wants copyright ownership so it
can make such threats effectively in pursuit of its special goals.
The Linux kernel, OTOH, has no contributor agreements (though it does
track who contributed what) and a multitude of copyright owners.
This is thought to be a strength.
