It is unclear if they are blocking paid/public VPNs only, which to be fair are no more secure than without, can you really trust some anonymous guy/gal who purchases a few random dedicated servers and VPSs at different global budget providers with providing a secure exit node? I can't see Netflix would have a legal problem with one running their own VPN on a cloud server within the same country, but I'm yet to find example of particular bannings.
