Yeah, sorry, that's just not how it works. It's not misleading to call something that doesn't interact with electromagnetism, and thus light, "dark", and it's not misleading to call something that is acting like matter "matter". Whatever hangups you have about these words are really on you. It's not even close to misleading, and even when the short terms given to complex ideas are "misleading", it still doesn't make them manipulative. Things catch on, and once that happens, it isn't getting undone. That's not a conspiracy to manipulate you.
