If Apple started routing all iPhone/Mac traffic through some anonymizing VPN by default, services that block it would absolutely lose lots of customers.
Quite frankly, it's a bit silly to paint Apple as some privacy fortress, who wouldn't have to comply with law enforcement/intelligence to unmask/tap traffic. I mean, for a lot of people VPN choice is done considering legal jurisdictions somewhere far away. Apple could/would never possibly offer this level of protection.
There were also plenty of corp-ware in existence that had Flash as *absolutely mandatory*.
