So they made their updates p2p? Why weren't they already? Feels like a no-brainer if you ask me. They need to be careful not to use my bandwidth in a way that I would notice (so basically when idle) and I also feel it would be appropriate to at least ask as there are some people who have data caps to worry about. A connection may be through wifi but still to a capped mobile broadband, such as when connecting to a smartphone. In such cases you often have a limit you unlikely want to use for updates to others.
