So it would be perfectly legal to do whatever I wanted with the source for GCC as long as there was a single fork on github that replaced the GPL with a MIT license? Quite sure the FSF would be perfectly fine with that.

I believe the person republishing GCC code under MIT would be liable.
Also, I'm not recommending that you use code you know has been incorrectly licensed. Just that in cases where certain "folk code" is seemingly widely available under permissive terms, Copilot isn't doing much that an honest human wouldn't.
A better example against Copilot would be trying to get it to regurgitate some code that has a simple known origin and is always under a non-permissive license.
