You do understand that they are merely statistics? He "owns" statistics . . .
That's like copyrighting sin, cos, or maybe even that outsider, tan.
Oh please.
He owns his measurements, his descriptions, and his photographs. We're not talking about natural phenomena here we're talking about him taking a plastic gun outside and firing it a few times at various targets, recording the results.
The NIC subsequently declares his work to be in the public domain because the NIC is comprised predominantly of lazy assholes.
Let me make this perfectly clear:
OKAY: Make a local copy of his reviews for your own personal use. This is exactly what happens when your browser caches files on the internet. It's an expected action when you place something online.
NOT OKAY: Make someone else's content available for viewing or download on your own server. This is a clear infringement of copyright law and is also just plain fucked up.
