"Mozilla is a one trick pony" implies they can't ship useful software. The definition of "product" isn't the point. If those products (or languages, or whatever) can't generate revenue that also wasn't the point of this thread. If one believes that Mozilla cannot create new things that the world finds extremely valuable, then things like Rust provide counter evidence of that claim.
