He obviously didn't mean to include people who are just tunneling back to their residential IP.
It’s not obvious at all. Netflix could be doing something as simple as checking the IPs or could be actually checking the use of VPN at a system level. Both are equally valid readings of the GP comment.
Any solution that requires me to reach behind my TV and plug in my laptop is already not easy.
With Netflix you just punch your password into your smart TV and you're watching content.
It even syncs progress across devices, works on all my devices (doesn't work in the Apple ecosystem).
