If you mention the consolidation of MSR labs including the closure of that in Mountain View, that was a bad move (in my opinion).
But, trying to understand here. My experience over a number of years is that experienced individuals are transitory...People move around. Depending on the group in MSFT and Satya's mandate, churn may make sense.
A decade is multiple tech lifetimes...Someone stellar 10 years ago may be on it now or may not...
This level of general MS bs on HN gets a little tiring when there are no facts.
I'm an apple household in general, but have multiple devices.
Cortana is superior to Siri, Google is still better.
But you make a post with no actual facts.
