There's no need to overreact about it either; no need to judge the book by its cover. To use your example, some people are having allergic reactions to the software as if it were named HitlerFS. The conflation is exaggerated. Dismissing great software because it was named after a man who would years later murder someone won't bring the victim back. It just eaves the world with less great software. Pointless and misguided moralism.

As I pointed out, this is not moralism. Humans aren't cold, calculating logic machines. We have emotions, and we care about our social standing.

If I choose to use a slightly inferor alternative because the name makes me uncomfortable, that is perfectly legitimate.

If using ReiserFS costs me a number of weirdness tokens (like using it in a workplace, and the relevant decision makers are likely to know about the murder now or in the future), then I may choose not to use it to conserve those tokens for other controversial initiatives that I care about even more.

Neither of those decisions may be "rational", but it's also not moralising. I simply have to take a complicated social/emotional calculus into account, something that most do unconsciously 24/7 without thinking "hmm, today I shall get on my moral high horse and decide that this is moral and the other thing isn't".
