I feel like BYOD was when the disease accelerated. It was the coup excuse for everybody and their mother to own a piece of your personal phone. Bank apps not working with rooted phones is pretty much BYOD 2.0.
Unless you’re clever about setting up the phones to match your excuse, you are now lying to the police as well.
Separation of church and state goes way back, maybe before the iphone.
