Because "private" here is regarding the cryptography and not regarding the disclosure? How are users supposed to obtain this key to use the service without it being published?
If the private key is public, it does nothing by definition and it may as well not exist!
Just use plain text, HTTP, or whatever and stop fooling yourself.
It’s like calling an open field a “secure facility”.
The name is not the thing, the map is not the territory.
Private keys are only private if they’re not public.
Get it? Get it?

We have to eventually ban accounts that keep breaking the rules like this. I don't want to ban you, so if you'd please review them and stick to them from now on, we'd appreciate it.
Nobody is surprised that Apple is able to revoke this key, by the way.
