Windows 10 privacy paranoia leads to ban from private pirate torrent trackers | Ars Technica
Again, the concerns around Windows 10's privacy impact appear to be tremendously overblown. There is the kernel of legitimate concern: Windows 10 collects a lot of data, and it's not as easy as we'd like to disable this collection. Windows 10 also seems to communicate with Microsoft even when configured for maximum privacy and minimal online integration. There are also reasonable concerns about what precisely is sent to Microsoft.
But these concerns are not "Microsoft is capturing the contents of your disks." They're more subtle; they're things like, "some requests are sent with a unique identifier, which would allow some searches and other online activity to be correlated." The inferences that can be drawn are not entirely precise, and there are concerns that they might be used for things such as targeted advertising—with, for example, the operating system using local search terms to influence Web ads—blurring the lines between "local" and "online" in a way that leaves some people uncomfortable.
