Re: My takeaway is...
I think it's more the opposite. All these technologies are new and enhance your control. I don't mean they're new in the sense of updated versions of old tools, I mean they're new in the sense of doing things that weren't actually use cases previously.
In the Olden Days, data was data and security was about not letting someone have access to your computer. Then it started to get more sophisticated and it was about having the right user accounts on the box, but if you could access the hardware you could still read the data off the drive. Then we started to see technologies that guarded data against physical access - TruCrypt, Bitlocker, et al. Essentially making security entirely about verifiable credentials.
Now we're seeing that taken to the next stage where entire "machines" (as in VMs) and processes depend on verifiable credentials. The uptake of the Cloud for people's platforms is actually driving the development of tools for controlling what happens and what is accessible that are even more capable than their predecessors. Because the Cloud makes such things necessary.
And ironically, governments' determination to spy on people is running headlong into existing business needs and pushing forward this technology far faster than it would develop on its own. MS have and will always have, one overriding goal - get your money. What we're seeing here, is them finding ways to code around the US government. The article is right to say that this will make the NSA howl.
And I have no problem with that. ;)
