This is such a conundrum. I used to love him before his move to Inter, but now I understand both sides' arguments. His contribution to Juve is unquestionable and one might even argue that he's still a legend despite the move, however on the other hand, he joined the most vile club, one that tried to destroy Juve and therefore can't expect loyalty from Juve fans. Him winning implies us failing, he's helping an entity that wants to replace us. Inter and Juve are total opposites, that's simply a conversion that doesn't work.
Each time I think I figured where I stand, I'm having second thought.
