It's a very long read. I'll sum up the main point but you should read it anyways.
Basically, match-fixing as an actual offence is under "Rule 6". They convicted Juve under Rule 1 (wrongfully). But, they literally made up a new rule to make it look like Juventus actually match-fixed. They said that Juve violated Rule 1 twice, and that it was equal to Rule 6. Hence the scandal.
And I don't deny that it is mafia heavy in Italy. But it's corrupt everywhere. Spain definitely, you just won't see them acting against it because they need to keep Real and Barcelona at the top. Italy is the only league where they're trying to combat it. The Marchisio thing is a complete lie. He's been at Juventus since he was 6 years old.
