Right, and we've added and removed exceptions over the years to deal with license incompatibilities.

Yes, you can see the license change in the Github repository - it is already live for the master branch which is tracking CUPS 2.3.x now...

I don't think static linking against libcups is common enough to be a serious concern - CUPS is fairly ubiquitous and easily falls under the "OS-supplied library" exception in the GPL 2. And existing GPL-2-only software that *does* statically link/copy CUPS code can continue to do so with CUPS 2.2.x and earlier.
