As much as George Hotz says that the settlement agreement is confidential, after reading them one can understand why he would want them to remain buried under the veil of confidentiality. According to those court documents, which have now been leaked to multiple hacking sites, and posted on Videogame247, Hotz was the losing party in the agreement.
According to those court documents, Hotz has been put under a "permanent injunction" that forbids him from "trafficking in any technology" that "circumvents any of the TPM’s in any Sony product," including any kind of decryption code or technology. He is also banned from assisting anyone else in such activities, or distributing and knowledge or confidential information related to Sony's products.
His hands are tied and his voice is lost when it comes to any Sony products. Further if he does engage in any activity that he is barred from in the court order, he can be fined $10,000 for each incident, up to a cap of $250,000. Should he violate the order, he also agrees that any further court proceedings will take place in California. In other words he agrees that the jurisdiction is officially California - apoint his lawyers argued against during most of his legal battle with Sony.
If there is one thing Hotz won it was that Sony did not ask that he pay any damages or legal fees. Still, Hotz's legal fees were not for free so he ate those, save whatever money he raised from donations and groups such as the EFF.
