I perceive you are an Italian taxpayer; I am not. As such, I respect your more vested interest in local taxation.
10 billion euros so far, and still growing, it's too much believe me
I can only say from afar, that Neos/Blue Panorama are small, leisure focused carriers with limited capability. They cannot be counted on to fill a "strategic" role in the national interest if needed (will they even fully survive COVID-19?). You may not feel this to ever be necessary, but I think its good insurance for every independent country to possess.
Neos and Blue Panorama combined have a fleet of about 30 airplanes, some of them are brand new B787 while alitalia has none of that. Do you know how many AZ airplanes are flying at a given moment nowadays? No more than a dozen, so I guess we don't need big airlines. Both Neos and Blue Panorama were involved to bring back italians stranded abroad, but only a minority, you know why? Because the government payed 53 M€ to alitalia for that reason, and gave nothing to other national airlines. Only private money is paying neos and blue panorama flights. The government a few days ago allocated 500 M€ to national airlines that "ensure a public service", do you know how many italian companies qualify for this definition? Just one. Nothing was allocated for other companies. Do you know that air italy just folded without one cent going into their pockets from the government to save them? Do you know that Ernest airlines, another small italian airline just folded without any help from the government?
Italy needs a national airline for moments like the one we are living? I can agree with that, but why we need this airline to be alitalia instead of neos for instance? The government should help healthy national airlines to grow and develop their business, but they are not doing that, on the opposite they are ensuring healthy companies face the competition of one large out of the market company that can sell at any price their seats because at the end of the year taxpayers will pay the bills, can you tell me what is the sense of this?
