...EU likes to humiliate the US and their corporations in whatever way they can... AKA their jealous... 
Why would the EU want to humiliate the US? Besides, the US is very capable of humiliating themselves right now, they don't need the EU for
that.
EU doesnt humiliate America they humiliate M$

And they'd humiliate any other company doing just the same. The EU is very concerned about monopolys (not the game), and they don't want any company to gain a too large market-share (like M$). Hence, if they see some company doing just that, they investigate and fine. Why they choose Media Player exactly, I wouldn't know. When Interbrew wants to take over a competitor, the EU also orders them to sell another part of their businesses so competition is maintained.
