Consider Dwarf Fortress. It’s currently not monetized (directly) and yet no one can come in and steal the business for themselves because nothing can replace Dwarf Fortress without an incredible investment. Wordle is basic as hell and was never built to be competitive in a market place. I bet the author would have lost to competition so quickly that the profits wouldn’t be as great as a lot of people think.
