What's so good about having Sweden? Or Russia? Or Portugal?
They are a European country, and are eligible to enter like any other European country. If their broadcaster wants to participate I don't see any objections. If that isn't enough, Italy has a rich ESC history.
They are in the big 5, because they contribute a lot of money to EBU, if they wouldn't, they wouldn't be in the big 5. If that's the reason why you don't want Italy in ESC, then you should not want UK, France, Germany, and Spain also.
They contribute a lot of money to EBU? WOW, and still ESC have been just fine without them. That's my point... They are direct qualified without doing anything for ESC itself. Let's see if ESC will be so much better with Italy's money...
Italy don't care about ESC. In Sweden it's very big. Sorry but Sweden would be a bigger loss to ESC than Italy.
I don't like any country to be qualified directly to final, but at least the other Big 5 countries haven't been abscent in over 10 years as Italy.
