You are being very hypocritical about this situation or you take it very lightly. Were all Juve players and fans in the know about the Calciopoli scheme, yet they were relegated? Were the fans at fault there or players like Buffon that have the integrity not to do such things, yet they were punished?
This situation is no different. The club owners/staff attempted a coup that would have had detrimental effect on the whole sport. They were doing it backdoors, attempted to create a rival competition to the one they are clearly against and to create a rich boys playground severing all ties with UEFA. Let's call it what it is - they attempted to create a cartel and feck up all the small clubs, creating a domino effect on the whole footballing world.
So because they didn't succeed they should be off the hook? What's stopping them making the same attempt in near future when they become more desperate for money? Do you think it's only the fans that stopped them last night and not legislation? They will find another backdoor and go ahead with their plan.
UEFA / FIFA are as corrupt as those owners, but without proper punishment it creates an exception that any club/s can attempt to separate and create whatever organization they like if it pleases their fans.. It's comical and farcical.
You can be precious about it and selfish all you want but if those boards stay as they are (changing one CEO puppet with another hardly makes a difference) they will eventually get what they want and couple of protests won't stop them.
So yes, harsh punishment is the way to take this forward, but we all know that the corrupt guys from the other side won't do that as they will suffer as well.
