iwhak, it seems you need some further information about this saga:
1. Regarding fares, alitalia has never used unfair competition. In fact it is usually know to have higher prices and poor service compared to competition. Instead, check a well know Irish airline for examples of fare dumping.
2. This time the rescue is made with private money (EUR 1 B). Yes there are subtle and not-so-subtle ways in which the state will be still sponsorizing the company, however no hard cash like it was in the past. Actually Italy will receive a payment.
3.There are founded reasons on which the EU or any other complaining party will claim that the previous injection of 300M must be returned by the future ownership. Be reassured, this will be the subject of hard legal and political battles.
Anyway, it's a done deal and those that don't like it, can only complain or write to your EU representative. See if they pay any attention and let me know.
And, as of today, there is no such thing like "the federal state of Europe".
