As can be seen above, current team members state that Google is running a smear campaign against both of them. We should emphatically not take Google's words at face value here either.
All of this increases my respect for Microsoft Research immensely. They've been more hands off and had researchers publish work critical of MS technologies. It's quite telling that supposedly more open Google is incapable of creating as open a research org as MSR, which remains in my view an excellent example of what an industrial research org can be.
