The thing is, the smart thing you hook up to it is under your control. It could be a laptop or Raspberry Pi.

Is a Windows PC really under your control nowadays? And if you connect your phone to the TV, you don't really even own those, even if you paid $1000 for your "phone". The manufacturers are the true owners unless you root them which is not always easy.
