I totally get this. I recently changed the license on my project from MIT to AGPL after getting a dm from someone interested in buying the project. I make absolutely no money at the moment, if anything I'm paying out of pocket for the domain, and don't think will any time soon. My only goal was to protect the project from getting commercialized by someone else. I've gotten questions about it and have been questioning whether I got too scared that someone might monetize what I worked so hard on.
