Someone, a real person, a human being actually came up with this idea and thought it was good. They then went to a meeting, a board group, discussion, whatever with lots of other people and they too all thought it was a good idea. Are all these people happy to be spied upon in their own homes? Not just them doing the spying on us? Maybe they all think they can have a secret backdoor that prevents them being watched or maybe they just get paid so much they really don't care about paying more so their pet dog can watch a film too?! And if one company gets away with it then it will become "acceptable" to be spied upon in your own home and every company will end up doing it.
