That is common thing in Italy.Supporters there will never forgive their lead player if he decides to go to another team and there are a lot of cases like this in Italy.The only player they respect is Francesco Totti who spent all his career in the Roma team of Serie A and people still love him today while his substitute which was going to be Daniele De Rossi left Roma and people still haven’t forgive him.
As you said only few players have been respected for having played basically their whole career with their respective teams: I personally recall Totti, Maldini and Del Piero.
