> That they own the devices you rent and you don't have to worry too much about it. You didn't need to worry about it because they did a sufficiently good job at making the choices for you. This is a sign that they stopped doing so. An appropriate metaphor might be a secretary. They can handle a lot of busy work for you so you don't have to worry about it, but they need access to your calendar, mails etc. to do so. This is not an intrusion as long as they work on your favor. If you suddenly find your mails on the desk of your competitor, though, you might reconsider. That, however, does not mean that the whole idea of a secretary is flawed.
