I'm quoting the plain text of the license. Section 5(c) for you:
c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy.
This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged.
I don't understanding what it's implying, you say? That's not an implication, that's a plain declaration, and in case anyone was too dense to understand
"you must license the entire work, as a whole", they repeated it AGAIN, saying "the whole of the work, and all its parts".
As for "if you're using the stock GPL license" look at the VERY FIRST LINE of the license, even before the preamble:
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
So yeah, you're using the stock GPL license. Funny you want to act like you're an expert on the GPL, even though you've clearly not even read the FIRST LINE of it.
Seriously dude, it's okay not to be THEexpert on everything. You don't have to act like you know more than everyone else on every topic and act like I"M clueless when
I've actually taken legal action under the GPL, so I kind of know WTF it says. Next time, instead of arguing from ignorance, try reading the darn thing and learning what it says. It's not that long.
