I don't understand how this response relates. It's still a huge ethical issue even if those people who are aware of it can learn to avoid it.
> That would have serious legal implications, so I don't see it.
I'm not as optimistic. ISPs have gotten away with modifying websites in the past, not as maliciously as this. But it's a step down that path.
> Or, you know, turn off the free wifi they are giving you?
Obviously I myself am not going to use the wifi. But I don't think just telling everyone you know not to use in-store wifi is a good long-term solution.
