If I had to make a guess, I'd imagine it was a misclick. Perhaps he meant to move it to reputation since its about the reputation of hardware manufacturers? The two boards are right next to each other when moving a thread. Its really easy to make that kind of mistake.
I'd move it back for you, but in case I'm wrong, I'll wait a bit to see whats up.
As you say though, its about hardware manufacturers and was busy sitting on probably the 10th page. Why now the prompt to move it after 100k views; its too spooky.
