IW10 came from Google and obviously was implemented in Linux first because that
is what they use.  However, and this is the big difference, they also provided
significant real-world data on the effects of their changes.  TCPM was very
skeptical at first but the data from the experiments has convinced many that it
is not harmful first and actually beneficial second.
