The EU woke up too late for that MS/IE situation, but it did lead to some massively good thing (in my opinion): documentation of office file format, of SMB protocol, decoupling on IE and Windows Media Player ("Windows N" was funny, but the decoupling was real and is still to this day), etc ...
That's why I hope for them to react to this one. The EU has been stepping up lately about making sure enforcement match the rules.
