It was a personal conversation. No link, sorry. From memory, Kurland related that the Xanadu team did one or more complete rewrites, couldn't or wouldn't commit to releasing something (delays), and Autodesk finally lost faith/patience. Kurland's a great guy. He didn't name names or dog their effort. He was mostly disappointed, because he had also believed in the promise of Xanadu. But that's just my take.
