/co/ exists for a reason. The word アニメ is an abbreviation of the japanese word "アニメーション", which is the transliteration of the english word "animation". Sure, that's granted if you know some basic japanese.
But when the word "anime" is borrowed back to english (or any other western language for that matter), it becomes a loanword on said language, that refers exclusively to animation made primarily in japan, and more importantly in the japanese language for the japanese market.
Conversely, let's take the japanese word "ハンバーグ". Phonetically, it's a transliteration of the english word "hamburger", but it doesn't refer to the meat on buns with vegs and sauces we know in the west - it actually refers to salisbury steak.
Or take the spanish (as I'm a spic) word "sombrero". In spanish, it means, just, a hat. Any hat, unless it's a casual one like a baseball hat or a beanie, called "gorras" or "gorros". But if it's, say, a cowboy hat, or an euphoric fedora, trilby or bowler, or a military hat (unless it's a helmet, called "casco"), or a felt hat... they're all called "sombreros" in spanish. But, when you use the word "sombrero" in english as a loanword, it's what in spanish is called a "sombrero de charro", a big, ridiculous (or, well, flashy, but still) hat used by mexican mariachis.
So, no, RWBY is NOT anime even if it IS アニメ - its main staff wasn't overall japanese, nor was it made originally in japanese (though it has not only a fantastic official japanese dub that I enjoy more than the original english, but a pretty good fan-made japanese dub that came out years before the official one, too), nor was it made primarily with the japanese market in mind.
But it does belong in /w/ and not just in /wg/, because it now has a japanese manga, and there's been other material released exclusively for the japanese market, like the artbook featuring big character designers and mangaka from japan.
