This is more like "killing a process" ("but people get killed"), "deleting a file" ("minorities are getting erased", "you aren't even removing anything, you're just changing some bytes, so it isn't even accurate"), "touching a file" etc.

It matters what you read into it, but that's mostly you, not the word. Is MariaDB sexist because it's a software that is expected to silently and flawlessly do things for you for free so of course it was given a female name, or is it a programmer's dedication to his daughter?
