alt Hacker NewsIt wasn't unhackable and decrypted versions of games already have been dumped. There was even a public exploit published years ago.

What's new here is that this compromises the entire system security giving access to the highest privilege level.
Thanks for the mention! I helped with the collateral damage exploit (wrote the PE loader).
I didn't ask but Emma -- who wrote the kernel-mode exploit -- and I would probably agree that Collat is not really what we would consider a proper hack of the console since it didn't compromise HostOS. Neither of us really expected game plaintext to be accessible from SRA mode though.
