They need a cute mascot, with a name. Then when people go "ew, it has a bug in it's name !!1!" we can say, "Aw, what's wrong with bugs? You're making Ricky cry."
I don't think its just that it has a bug in its name. I would venture to guess that if the name was Wasp DB, this issue wouldn't exist. It has more to do with the disgust trigger that many people have when they think of cockroaches.
