This is quite interesting, but governments (especially the EU) have this knack at completely botching anti-trust cases.
For instance, the cases against Microsoft, the settlements were for them to create a version of Windows XP known as XP N, which did not include Windows Media Player to prevent distortion in media player markets. The results, 35.5 million copies of the full version were purchased in Europe, 1787 copies of XP N were purchased, representing 0.005% of sales. Other than the fine, the resolution was completely useless. 1
Then the browser settlement with Microsoft forced them to include a browser selection screen on their install process, which is mostly done by OEMs and tech support for the average user anyway. This screen looked like this and offered about 12 different browsers to choose from. It was discovered that for 17 months after SP1, this functionality was not showing up and nobody noticed. 2.
Unless their goal is to just be a thorn in the side and occasionally fine them for being big, US and EU has been completely ineffective at breaking up malicious monopolies and dealing with anti-trust cases at this point, so I see this going nowhere other than getting the EU some spending cash (which hopefully they'll just donate to Greece or something).
