"Why did Microsoft choose not to use existing code? I cannot say. The license allows them to use the existing code as is without legal ramifications."
"However, despite legal availability of the code, it was not used and this allows Microsoft to open the floodgates. Since they wrote their own code, they are not, nor ever were, bound to the M.I.T. license. This means that even if the code had been released under the GPL, Microsoft could have released a new version with proprietary extensions without violating the M.I.T. license or running afoul of the law."
"So we are now left with Leibovitch's article, which is clearly designed only to attack BSD systems. Leibovitch states that Microsoft's treatment of Kerberos is an example of real harm to the free software community that occurred because a BSD license was used. But as we have already seen, the GPL could have not have prevented it."
