You could equally argue that, in my corrected form of your analogy, the motorcycle manufacturer has not been negatively affected in any way. They may be upset that you have obtained a perfect replica of one of their motorcycles for free, but you would argue that you weren't going to buy one in the first place.
So, can I ask again - in the corrected form of your analogy, do you think that would be fair to the motorcycle manufacturers?
Any analogy can have holes picked in it as no two situations are every 100% the same. For example, creating a duplicate motorbike is not free and is not without effort. If someone were to build a replica bike, I do not believe Kawasaki would care, unless they were selling those copies. In the same way as people build race replica motorcycles without drawing the ire of the manufacturers.
But back to the actual topic of the thread. The BBC news story isn't about piracy being right or wrong, it is about censorship. It is the censorship I disagree with.
You might disagree with Piracy, and I would hope you disagree with child exploitation, but closing the door on these things and pretending they don't happen (as we all know blocking http access to one nzb aggregation site will not hamper piracy when there are other sites, and VPNs) is not a solution.
First they came for the communists,
and I didn't speak out because I wasn't a communist.
Then they came for the trade unionists,
and I didn't speak out because I wasn't a trade unionist.
Then they came for the Jews,
and I didn't speak out because I wasn't a Jew.
Then they came for me
and there was no one left to speak out for me.
