After the release of our blogpost, it is very funny to see Mr. Stefan continues to post unwarranted and spiteful conjectures on Twitter and his blogpost. We suggest the reader refer to our blogpost as well as his blogpost to understand the backgroud.
Among his numerous discriminations and accusations against us (such as calling us thieves and criminals), the main one is that he claims that we have been trying to buy/acquire vulnerabilities to achieve jailbreaks. The “horribly” strong evidence is a piece of chat history between him and @windknown, a member of our team. Although we think it is immoral to post private messages to the public, we do not mind showing the full chat history, and let the truth speak for itself.
