Смысл: The main idea is the successful reverse-engineering of the proprietary Skype Network protocol to create a free, third-party text client (Epycs Messenger), highlighting the tension between corporate closed-source software and the open-source community's drive for transparency and interoperability.
Developers have created Epycs Messenger, the first open-source client to connect to the Skype Network via reverse-engineering, despite significant security flaws in the code and legal pressures from DMCA.
Смысл: The main idea is the struggle for interoperability between a corporate service provider (AOL/ICQ) and independent developers, illustrating how community collaboration and reverse engineering can overcome restrictive corporate attempts to monopolize a user base.
AOL attempted to block alternative ICQ clients in the CIS region by changing protocol requirements, but developers from Miranda IM and QIP quickly bypassed the restriction through collaborative reverse engineering.
Смысл: The text announces the release of a deobfuscated binary file for Skype version 5.5, enabling developers to use debuggers for reverse engineering. The ultimate goal of the effort, led by Efim Bushmanov, is to create an open-source version of Skype.
A deobfuscated binary of Skype 5.5 has been released to allow debugging and the potential creation of an open-source client.
