I'm speculating, but I'd guess this was the fault of poor management of an external contractor or partner. We don't know for sure who actually developed the code, just who's hosting it. It's not like similar things haven't happened before: http://arstechnica.com/microsoft/news/2009/11/microsoft-pulls-windows-7-tool-after-gpl-violation-claims.ars http://arstechnica.com/microsoft/news/2009/11/microsoft-pull... I'd personally never heard of Plurk until now, and wouldn't have known myself that a contractor had ripped it off had I commissioned the work. It's still an egregious violation, but I doubt this will even need to go to trial. Microsoft stands to gain little from alienating startups in this manner. If it comes to it, I'm sure aggressively shaming them publicly will be far cheaper than suing and eventually as effective.
