MIT can be relicensed as GPL. GPL cannot be relicensed as MIT. If they wanted to use the wrapper, they should have released as GPL. I'd they didn't want to release as GPL they shouldn't have used GPL code. It is that simple.

Moral of the story: avoid GPL code, unless you really want to deal with headaches.

More like: Avoid GPLv2/3 code if you plan to keep your code proprietary and distribute binaries. Avoid GPL Affero if you want to keep your code proprietary and it can be reached over a network by clients. Use GPL if your code can also be GPLd or you aren't going to be distributing it/giving it network access to clients.
