R6RS Implementations and Licensing

Why are there no good, free, and non-GPL R6RS Scheme implementations? How the fuck am I supposed to embed this into my applications when I'm forced to fucking release the source code to the rest of my software under GPL. No wonder it doesn't have a lot of community adoption outside of academia and the open-sores community.

The reasons that Scheme does not have wide adoption are well known, and none of them are due to licensing.
It's because it's slower than Ruby, has less libraries than Ruby, and requires more typing than C.
