I think its good to always be highly skeptical of all technology these days. I don't mean that we should do so in a tin-foil hat sort of way... but we should question everything. I saw a post on HN just a few days ago about how Vizio (the low-cost TV supplier) was wholesale collecting and selling all usage information to a third party... without users' consent. Its good to be vigilant and ask the "dumb" questions sometimes...
