Today I received a copyright infringement notice from Sony’s lawyers, asking me to remove a file we’re hosting here at wololo.net.

The file is a zip containing an old version of CTurt’s open source PS4 SDK, of which the original can be found on github here, and has been there for years now.

I’m pretty convinced (note: not a lawyer!) that CTurt’s work does not consist in copyright infringement. However what’s much more interesting to me is that this does not seem to be the work that Sony actually are after.

Instead, it appears Sony have launched a witch hunt against a recently leaked version of their (official) PS4 SDK, a leak from a team named KromeMods.

A few other scene websites including playstationhax have received bogus DMCA complaints. Playstationhax had to take down an article reporting on the leak. The PlaystationHax article was not linking to any copyrighted material, and yet they have been asked to take down their article that was merely talking about the leak. We, here, at wololo.net, have been asked to remove a file that is not connected to that copyrighted material, but shares a similar name.

In other words, Sony’s lawyers are visibly doing some broad keyword search and blasting website owners and internet providers with takedown notices for everything that remotely looks like it might be related to the copyrighted file. Hey, that’s cost effective I guess, more than actually confirming if actual copyright infringement happened or not on the sites.

Of course, some sites where the leaked SDK was actually being distributed, including mediafire, have taken down the infringing file. Scene websites that were distributing the file have either removed their links or made their articles visible to members only. Again, we at wololo.net didn’t even discuss that PS4 SDK leak until today, let alone distribute it.

For now, I have decided to not take down CTurt’s SDK. I replied to Sony’s lawyers that they made a mistake with their takedown request for the files we host. Obviously, I do not have the intent to fight a long legal battle if they insist, and I might have to remove CTurt’s files from our server, even though that would be a collateral victim of some unrelated battle.

For reference, Sony’s Lawyers’ statement below (because the best way to fight abusive take down requests is to make them public):
