No, it is a confirmation biased article from someone who doesn't like Apple devices in the Enterprise IT structure. . . and it will be quoted ad nauseoum by others who also have that attitude and see it as confirming their biases and want to keep Apple devices out of IT in the Enterprise and keep the Enterprise as a Windows only bastion.
The article is from someone who's apparently selling third-party software to help IT departments manage and enforce security policies on Apple devices. Why would they not like Apple devices in the Enterprise IT structure? They'd be out of business without them.
