MIT is relicensed as GPL, under the GPL 2.0. By including it as part of the whole, the whole becomes GPL.
And... It is surprising to me, that anyone can think otherwise, 2 decades on from D-Link [0].

Which is something you start to say, and then say it isn't the case.
The whole just becomes GPL v2. That's the virality.
