It's our duty to make Conte's life harder. Even if it wasn't for Agnelli's war with Tavecchio, which is actually the main reason for Juve's attacks on anything related to the FIGC, including the NT coach, we are simply obliged to kick Conte at any given chance.
Juve is an institution, while Conte is just an individual that, conscious of the consequences or not, screwed up the institution. His resignation in such sensitive timing could have cost us lots of money, screwed up the locker room atmosphere, led to departure of important players, and fucked our reputation. If we don't make it clear that similar actions will be punished hard, we're leaving space for other individuals to do the same in the future. This time we survived Conte's resignation, but tomorrow we could indeed lose lots of money and players if someone else decides to fuck with us Conte style. That's why we must do what Moggi did with Zeman. We must make an example of Conte by screwing him really hard, so everybody else will be scared to even think of doing something similar. By destroying Conte we are actually protecting Juve, so it's a no brainer to fuck him up everytime a chance presents itself.
It's naive to just let it go, leaving it to the fact that we proved how we're bigger than an individual. Nope, we must make sure that this won't happen again, and we'll do it only if we make sure that people will see what happened to Conte, and they'll be afraid to do what Conte dared to do to Juventus.
