Until they get "smart" enough to connect via someone else's WiFi hotspot within range.
If you think this is a joke or some sort of silly conspiracy theory, please consider the scheme BT already operate across the UK where you can piggy back on other people's home broadband to get wireless Internet access. On my fairly typical residential street, I already have several homes within range of this computer that are part of that scheme, which any wireless device in my home could be connecting to without my knowledge or consent, including those with access to my home network or that include equipment like cameras and microphones.
I expect BT could make a tidy profit from making deals with these kinds of companies so they can phone home using their built-in wireless without depending on the customer's own Internet provision, and given their track record, I have no reason to believe they would object to their networks being used for the purposes of intrusive surveillance. I am hoping that laws against these in-home privacy intrusions will arrive before it becomes the norm for consumer products to use the national wireless spynet for this kind of purpose, but given the way the market is going, I am not happy about our prospects on this one.
