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.

Unless you've implemented R6RS (from scratch, not just forking an existing R5RS or R6RS implementation), you are not in a position to judge it.
