Only because they don't know what is going on.
There's also a belief in the false idea that, "they already have all of my data, so there is nothing I can do about it."
It's arguable that one needs a mobile phone to participate in modern life (and the situation with mobile phones requires fixing as well). It is not arguable that people need to be able to talk to a box that makes them a coffee or turns on a light.

Don't underestimate the domain knowledge that you've acquired, and the amount necessary to root a phone, let alone take control of linux embedded in a television. It's about more than just not knowing that we're being spied on. It simply isn't efficient to expect so many people, who have already specialized according to their professions and interests, to also take on this level of domain specific knowledge.
