Facebook also has all rights of your photos.  Why is that such a big deal with none us services?,(reply>), Well, you choose to upload your photos on Facebook, so you are actively giving Facebook that authority when you use it's service to host your photos, nothing wrong with that as you retain the choice not to use the service. Cortana seems to re-enable when windows updates and you HAVE to update windows eventually so you don't have the same level of control over Cortana and your data unless you do a bit of tinkering with the Reg and Firewalls...not everyone will know how to do that and it's an ethically dubious at best to exploit that.
