Graf_chokolo, famous for a multitude of decryption payloads, has warned Sony to back off. Earlier today, several sites were issued Digital Millennium Copyright Act (DMCA) notices, ordering them to stop hosting several famous PS3 dev's projects. Sites such as GitHub complied with the order, and removed projects being worked on by coders Kakarotoks, Graf_Chokolo, and Kmeaw.
In response to these actions, earlier today on XorLoser's blog, Graf_Chokolo gave Sony an ultimatum. He stated that if Sony was to continue such tactics, that he will publish his IDA database, for the PS3's Hypervisor and Hypervisor processes. What this means, is that reverse engineering the hypervisor would immediately become much easier for other developers using IDA Pro Disassembler. IDA Pro is a popular tool, commonly used in reverse engineering software.

No fear, jack :-) It just motivates me more to continue my reversing :-)
It was just my public GIT repo, for making releases :-) Nothing lost :-)
