Weird that early in the issue comments the author claims they're going to release source for fuse-t, but then later in the comments changes course and says it's proprietary. Sounds like they originally wanted to release it as open source, but under a restrictive non-commercial license (which is fine, I guess), but then has gone back on that promise.

I'm not gonna be one of those "proprietary software is immoral" people, but it just rubs me the wrong way to see someone take a concept/protocol that was originally developed in the open and released as open source (the Linux version of FUSE itself), and then build something proprietary.
