Is there a particular aspect of the FUTO license you are concerned with? The code is publicly available, and the license seems to allow you to do anything you want, except sell the code. Other than not allowing you to re-package and sell the code, it seems like your rights are very similar to anything distributed via the GPL.
Am I missing something?
According to the license, it is better than source available. You can modify and redistribute, you just can't sell it. Other than that caveat, as far as I can tell, your rights are basically the same as with other open source licenses. (Feel free to correct me if I've missed something.)
