I'm not defending CM in any way but this lawsuit is dumb. Marketing misrepresents products all the time. Ever seen a fast food commercial? Notice how the burgers always look about a million times better than the burgers you actually get?
Unless a product explicitly advertises a feature it doesn't actually have, it's not considered false advertising. For example, if a TV is advertised as being 50 inches but is actually 20 inches, that's false advertising. However, if a TV promises the best image quality ever but ends up being shitty, that's not false advertising because image quality isn't quantifiable and largely subjective.
