I agree with your point about the licensing. I would also add that tools for the development of compiler front-ends are quite a niche market. So, honestly speaking, I don't plan to earn much from my project regardless of the license terms. This work is part of a higher-level in-progress toolset, which is closer to the end users. I have dedicated it as a separate project primarily for public preview, with some restrictions on distribution and use, as I haven't decided on the overall toolset distribution model yet. But it is possible that I will change the licensing terms of Lady Deirdre in the future to something less restrictive (maybe even MIT) to make it more popular, this is just not my current goal. I apologize for any inconvenience my current licensing terms may cause.
