Just like the idiotic arguments about app store rules being there to ensure quality, etc.
Apple is really good at putting a spin on these kinds of moves, taking anything they claim face value is extremely naive.
Apple ought only be allowed to reduce iOS data exposure if they also take steps to assure the market that they are not gaining undue advantage over their competitors. Apple customers should be aghast at the blatant move to harm legitimate companies such as Facebook and Google. With iOS data opacity, as opposed to data transparency, we have a less competitive marketplace.
