I didn't read anything regarding the potential security issues of this, but... Remember the Twitter exploit of 9.3.1 that let anyone see photos/contacts using Siri? It was fixed, but fixed server side. So that means Apple can pretty much have Siri do anything iOS supports - server side. http://thenextweb.com/apple/2016/04/04/ios-9-3-1-bug-lets-talk-siri-giving-photos-contacts/ I'm a little surprised that I haven't come across anyone complaining about the obvious ramifications of in terms of what Apple can get access to if it needs to..
