I don't think that this fine has anything to do with MS or computers or OS.
The EU needs a lot of money for their intention of expanding to the east. Ar the moment they are short of cash.
They are at the moment trying to put a lot of pressure on Switzerland in order to receive more money from them.
The EU is trying to get money where they can and where there is. I wouldn't be surprised if MS will remain the only US company which will get fined.
After all the EU has learnt from the USA which used and will still uses this strategy to keep their own companies competitive and to fill their own pockets.
This is simply an economic war but don't worry... no blood is involved.
