Here is an excerpt from the article:
"While it's incredibly clear what Microsoft means by “counterfeit games”, the wording “unauthorised hardware peripheral devices” is a little hazy. Does this mean Microsoft can now block uncertified PC or illegally-modified Xbox One and Xbox 360 controllers? Furthermore, Microsoft's EULA doesn't state if it will also disable other counterfeit software, such as cracked versions of Office or Adobe Photoshop, or if it only cares about pirated games."
What about useful or specialized "abandonware"? (Software that is no longer supported because the original company is no longer in existence, but is still useful.) This could also affect specialized hardware, or even custom hardware/software. A false "positive" could be devastating, especially in a manufacturing setting.
