https://github.com/aseprite/aseprite https://github.com/aseprite/aseprite This software uses a license that seems to solve both the problem of ensuring the user has control over the software and also allowing the author to sell and distribute binaries without worrying (too much) about others undermining his control over the market. It appears to work quite well in this case. Although I do not know how much he actually makes from software sales, it appears to be non-negligible based on its popularity within a niche community and the fact most users would rather pay $15 than learn the skills necessary to compile from source.
