Apparently, the cool thing to do is now to defend Microsoft, actually, even in the face of ridiculous transgressions and clear unlawful and unethical behavior. I can't believe that people are giving them a pass on this 'oh, a 3rd party developer did everything and it was all their fault!' excuse. Somehow I doubt that Plurk was elated to find that a giant corporation had thoroughly imitated their site. Probably, once they saw that the exact code had been lifted,it was a relief, though, as they knew that couldn't stand.
