Inter has 17 scudettos. Yes, we have the most fans in Italy, but we also have the most haters in italy (historically). I never underestimated the size of Juve, because theres no bigger club than Juve, only the same size such as Real madrid, AC Milan, Man Utd etc...
Inter is a very big and strongItalian team, Juve is the biggest and mighiest in Italy (historically), and fans will always be fans (unless they are bad supporters), so if the clubs are cheating, there will always be fans to support the team
