No, it doesn't (I even bold-faced it for you). What happened previously does not relate to anything that previously happened between MS and Apple.
If you blatantly rip off someone's product, you can sue their ass. Why people think that's somehow abnormal is beyond me.
What makes you think Samsung ripped off Apple?
Samsung had their smartphone earlier on the market than the first iPhone. The first iPhone was released in June 2007 on the market, while the Samsung phone was released february 2007 on the market.
