We've just been over this. Popular decision: It isn't off-topic. Taken from my answer on this:
I don't believe that question is a good example of a question that isn't about Ubuntu. Ubuntu is currently installed, the longhand way of reading the question could be: What do I need to do to Ubuntu to get rid of Ubuntu and prepare for the reinstallation of Windows?
And that might very logically have plenty of Ubuntu-related things in its answer. You might need to unmount the firewire matrix from /proc/, or defragment the boot partition, or patch the 802.11 antenna array for parity switching. The person asking doesn't know. That's why they're asking. In short, that the answer doesn't neccessarily need to be Ubuntu related, doesn't mean the question isn't on-topic, even if only tangentially.
Yes, there are also popularity, "what makes us better" and dupe-target arguments that I might weigh for a more contentious topic, but I feel this question is entirely within our scope.
You clearly don't. And that's okay too.
