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.

Why would you expect a defined process? It's proprietary software on a closed platform.

I'll just take your word for it that there's no ways for Texans to get the same treatment as these other companies. Oh well. Take it up with your legislature, I guess.

This is a pretty unfortunate context for this, but I just wanted to say that I've been using your service for years, and me and my handful of customers are 100% satisfied.

It sucks that Apple won't just embrace interop with host mail services in some formal way, I'm not sure what the benefit of this specific flavor of gatekeeping achieves. It also sucks that HN contrarians are reflexively dumping on this, instead of supporting entrepreneurs like one might hope in such a community. Anyway, keep up the great work, I'm with you long term.
