Enabling Exchange account on your iOS makes the device pwned

Seems like a lot of people are not aware of this "feature".

Using Exchange ActiveSync allows the device to be remotely wiped. Don't like it? It's your iOS device. Don't use ActiveSync.
At my job, part of the process of enabling ActiveSync on a personal device is signing a document that says you understand what "Remote Wipe" means.
If you don't sign it you'll get a company Blackberry/Android.
Honestly I consider remote wipe a very useful feature. In addition to whatever if-it-phones-home-we'll-nuke-it-from-orbit capabilities that iCloud provides, my own personal email is via a hosted Exchange provider and I can remote wipe my devices through it if I want.
Heh, BlackBerry was the first vendor to offer such a feature, AFAIK. It's the primary reason my previous company rolled out the devices to the execs.
We also made it very clear that if your device was lost or stolen (or you got shit-canned), it would be wiped as soon as possible no questions asked.
The point is to avoid the intersection of "work's phone"/"my phone", not to avoid iOS.
