Not much of a hate but rather protecting their IPs by avoiding licenses like GNU. They are not alone in this, most of the big companies are avoiding it. Some companies use it and hoping for not getting caught (VMWare). I still don't see hate here, MS is just smart enough to avoid these sort of situations.
Microsoft haters are on record as attributing all manner of emotions to Microsoft decision-making, but from a detached perspective it all seems fairly dispassionate, if sometimes overly aggressive.
No, as far as I know they fulfilled all GPL obligations on the SFU stuff. And I know of no cases of Microsoft violating the GPL (and I would have heard if there were). Not wanting GPL is entirely "won't" rather than "can't".
