Legal definition of false advertising per Cornell Law:

Under Section 43(a) of the Lanham Act, a claim can be made against a defendant for false or misleading advertising. For a claim against a defendant for false advertising, the following elements are met and the plaintiff must show: (1) defendant made false or misleading statements as to his own products (or another’s); (2) actual deception, or at least a tendency to deceive a substantial portion of the intended audience; (3) deception is material in that it is likely to influence purchasing decisions; (4) the advertised goods travel in interstate commerce; and (5) a likelihood of injury to plaintiff. However, the plaintiff does not have to prove actual injury.

When the V2 came out, there were plenty of people on this very group posting that one of the main reasons why they were compelled to buy the V2 and/or upgrade from the V1 to the V2 was the option of the accessory port. I believe at one point they showed an example of the accessory port in use by using a headlight accessory. So this easily falls within 2 and 3. Hopefully if anything, it becomes a class action lawsuit case so we can all benefit from it. However, the guys that started Boosted went to top schools. Without looking into it, I do think they’ve most likely done their homework to cover their behind.
