Not even the worst reading of their reply would lend to that implication.

It’s pretty obvious that they meant that anyone who depended on their service would/should probably run away kicking and screaming if they were looking for a dependable service that will do what they claim to in the long term.

If they were Apple sanctioned, then at least you’d have some reassurance that the service won’t die randomly one day when Apple has had enough, à la Beeper.

First, that's pretty obviously not what I said. Two things can be true. This is bad, and also if I were evaluating it for use in my business, it is obviously not something I can rely on.

But then just ...Um yes? I trust Apple to keep a handle on their iMessage network. Citation: having used iMessage for ~15 years. This would mean things like ensuring that I didn't get spam. Ensuring actual company identity (does anyone remember Messages for Business?) &c. This is pretty obvious and I am trying to understand your comment?
