Except of course via Chinese access to the unencrypted cloud as required by their laws. Who as we've seen this week, is willing to sell to anyone.
And I'm not sure what we "seen this week". If you mean the link posted below, that's unrelated from some "unencrypted Cloud" -- it seems to talk about data on Apple customers (names, addresses, email, numbers, etc), from some POS/CRM system or such.
It says "The suspects allegedly used an internal company computer system to gather users’ names, phone numbers, Apple IDs, and other data, which they sold as part of a scam worth more than 50 million yuan (US$7.36 million)."
So this is about CRM style data being stolen.
