I don't think it's fair to assume everyone here knows the characters original names either. Especially when we are referring to two minor characters who barely get any significant screentime and for the most part are just there for exposition. I know people that just refer to them as "the lab assistants."
Sure. But those people are still regularly hearing those names, because those are the names used in a version they watch.
Nobody's saying you HAVE to use the original names, this is just a reminder that this is not a place where you're surrounded by people that necessarily watch the dub and know what the dub names are, so you may be confusing others by using them. Everyone here do however follow the Japanese original and get regularly exposed to the original names.
