There is no defined process for obtaining it. If you'd like to tear down that statement into little pieces and dissect it, I recommend getting a new hobby because it's not that interesting.
MXroute doesn't go around threatening US companies with EU law from Texas. As for your requirement for evidence, this situation does not require your approval unless you work for Apple and can offer some help in the matter. The tweet you are critiquing is me (owner of MXroute) attempting to gain Apple's attention to get what Fastmail and that EU user have obtained. I'll continue doing what I'm doing, if that's alright with you. I'm well aware of the situation and what others have done. What I need at this point is eyes on the prize. I'll get what I'm after, but a public statement that I currently cannot get what I'm after is entirely appropriate for the avenue I've chosen to do so.
It's a mistake to assume that I'm merely flailing my arms chaotically and generically playing the role of Karen.
