Re: Just another attempt
"they currently have a controlling share in anything which has to work cross-platform.
e.g. chat apps."
They do? I think the dominant chat app is WhatsApp right now, which isn't an Apple product.
However, the point that DougS was making was that iPhones themselves don't have enough market dominance to allow them to be considered a monopoly. If there's no monopoly, then there can't be an abuse of monopoly -- so whatever Apple wants to do in terms of dictating what is or is not allowed to exist on iOS is unimportant in terms of this aspect of the law.
