No. Why do you think it is? If the business model is "connect to the mothership and feed us data at all costs", why wouldn't they just arrange with the ISPs to allow their devices to connect?
This paranoid alternate reality where tv companies are paying every ISP for backdoor access is very, very far away from flipping the “opportunistically join open networks” bit. It’s also not borne out by either research or logic.

Nothing works like that. They don’t care about you, beyond the pennies they can make. If it costs (and it would) they won’t do it.
