It's better not to connect the TV to the Internet at all. This will solve most of your problems. Use a Linux HTPC to stream content (not an Apple box, they collect telemetry and profile users like others).
What's your HTPC setup? I used Kodi for a while, but gave up on it as unsuitable as a frontend for netflix et. al.
