I've blogged about this (
broad summary,
helpful analogy).
It's interesting to see how the employer and the FBI totally blew it with the whole MDM thing. Like, they should have been able to do this, but they screwed up, so now they're using that as a basis to go after something they've really wanted for a much longer time: a deep legal precedent.
The challenge, so far as I can tell, is trying to come up with a compelling way to even
explain what the tech people are so upset about. The FBI's public statements are, needless to say, entirely one-sided on this.
