Are you attempting to assert that use of these files solely for the purpose of improving a software system meant to classify file types does not fall under fair use?
Here's another one for you: Do you believe that all pictures you have ever taken, all emails you have ever written, all code you have ever written could be posted here on this forum to improve someone else's software system?
If so, could you go ahead and post that zip? I'd like to ingest it in my model.
Your question seems orthogonal to the situation. The three files posted seem to be the minimum amount of information required to reproduce the bug. Fair use encompasses a LOT of uses of otherwise copyrighted work, and this seems clearly to be one.
I'm over here trying to fathom the lack of control over one's own life it would take to cause someone to turn into an online copyright cop, when the data in question isn't even their own, is clearly divorced from any context which would make it useful for anything other than fixing the bug, and about which the original copyright holder hasn't complained.
Some people just want to argue.
If the copyright holder has a problem with the use, they are perfectly entitled to spend some of their dollar bills to file a law suit, as part of which the contents of the files can be entered into the public record for all to legally access, as was done with Scientology.
No, I'm asking if he has permission to redistribute these files.
