There are many fine resources out there for you to read. I'd
recommend [1], [2] and [3] for starters. Yes, [1] is gnu.org:
one might think they have a bias -- still it's well structured
and worth a read.

The thing is: BSD, MIT and friends allow you to combine the stuff
with any other program and relicense the result as you wish (e.g.
proprietary). This includes a GPL work. The result is, then, GPL.

That only means you lose the protection afforded by GPL3 once you
assert patent rights (e.g. by submarine patents). Remember -- GPL
/grants/ you permissions to do things which, by default, would be
forbidden. So it only can revoke those things, if you are in breach
of contract.

Is it? It will strongly depend on jurisdiction, I guess.

Why should the patent grant be tied to the license of the end
software? Now, if the license explicitly states so, perhaps.

The patent grant in Apache2 is why the FSF recommends this one
among the non-copyleft [4] licenses.

[4] I very much prefer this term to the "permissive" you used in the
   subject: permissive is ambiguous. Permissive to whom? Users?
   Programmers? Distributors?
