The fact Elkann made zero effort to defend Juventus/the triade despite having what has proven to be a very strong case, demonstrates there was some sort of animosity between the triade and the new regime. Whether they actively contributed in our demise is another matter, and it would be impossible to prove, as pressure from FIFA/UEFA contributed towards our non-appeal as well.
In any case, blaming Blanc is pointless as he was placed there and takes his orders from higher up. Speaking of the higher ups, look at the defense of Ferrari when it was uncovered that McClaren were spying on them and compare that to the response to calciopoli and TIM spying on Juventus.
