Actually, I'm pretty sure that the exact opposite is true. When you
distribute
"under the terms of the GPL2 or later", that means I can accept
your program under the terms of the GPL3. The terms of the GPL3 say that I
can modify it and redistribute it under the GPL3. Similarly for the GPL2.
Notice the language says "*or* later", not "*and* later". I get to
choose
which license I agree to. Otherwise, it would be pointless to even offer it
under the "GPL 2 or later" because I would *have* to distribute it under the
GPL3, which places further restrictions on top of the GPL2, meaning that it
would effectively be under the GPL3 no matter what.
