A great difference between Nokia and, say, Zynga:
When Nokia killed MeeGo, they let Jolla take the technology and make a new company out of it when they could have easily thwarted it with any number of legal/IP/HR chokeholds. But Nokia looked the other way and let Jolla continue.
When Zynga killed OMGpop (of "Draw Something" fame), the original people wanted to keep OMGpop going, and even offered to buy it back from Zynga. Zynga refused and insisted OMGpop's remains be destroyed.
Good Guy Nokia
