According to that article, which was written by a known Microsoft hater, by the way, the Enterprise version will be able to update when they please, the Pro version will be able to delay updates for 6 months, and the Home version will have the updates pushed.
Here's the thing though, you can just block the Windows Update IPs on your firewall/router and make it impossible for them to be received by your computer. If this is legit, then there will quickly be guides on how avoid having updates pushed to you, if that's what you want.
As the saying goes, when something online is free, you're not the customer, you're the product. In Windows 10's case, they are using free versions to test updates for the paying Enterprise customers, to give them a level of guarantee that their updates won't break the OS or the various software.
My plan is to pay for one copy and keep my other two computers on Windows 7. I may switch around which computer has which copy though. If there truly is no way to only update when I want with which updates I want, then I just won't update, or if I end up needing DirectX12 for some game I want to play, that computer will be used for the games and nothing else. But I find this possibility to be remote in the extreme. I've got some Cisco certs and I can block Microsoft's traffic in my home network, they can't get around that.
