The problem is that in the age of the internet, it's very difficult to find anything that someone, somewhere won't be offended by. Every time an organization or project gives in and alters its innocently-chosen name because a tiny minority takes offense, they further normalize outrageous outrage.

It's definitely a fine line to walk. There are names that originated in an offensive context, and it's easier for me to see the objection to those. But "lunatic" hasn't been commonly used in its offensive sense in nearly a century, so I don't think it's fair to stoke outrage towards a project that started in the 2020s and chose it for extremely innocent reasons.
