...or just don't show it if it's not available. It is sort of interesting to know that information, but it's not like I have time or interest to contact the rights holder in some other territory and promote the potential economic gains of cross-border availability.

Also, I wish the same were true for mobile devices. I am heartily sick of being told 'x is not available on mobile' or spoofing the user agent string in my tablet to watch something. It's really none of a publisher's business where I choose to watch something and this attempt at artificial market segmentation is not worth the administrative overhead it imposes.
