I usually use MIT, partially because my current interests (AI/LLM stuff) involve interfacing with some other projects that are MIT and partially because it’s just a simple “do whatever” license and I don’t really care to enforce terms. Of course, if I thought some government or company was going to use stuff I develop to launch the nukes or control a robot fist to punch cute little puppies right in the snout then I’d start using a more restrictive license but the odds of that are… pretty much nonexistent for everything I’ve ever created.
