Fody says they have an “honesty system” and expect all users to pay, even if they’re not raising issues or PRs. That’s despite the fact that the code is MIT licensed. How is that a more ethical, straightforward, or profitable business model than just GPLing the project and offering proprietary licensing? Releasing code under a permissive license, then calling people dishonest when they use it according to the license but not the authors’ desires, seems silly and inefficient.
