I think you're being quite unfair and missing a bit the context. Back then Mourinho just returned to Chelsea. Their best manager ever, arriving on a white horse to bring glory. It's no wonder the fanbase believed every word of his personal attacks on departing players. It's only after he started to have public meltdowns and nearly got them relegated when eyes where opened.
It's not hypocrisy, sometimes you can just change your mind.
I think the whole drama is just silly. Shaw very well might have bad attitude. But it's worth noting all the managers who had complained about him. LVG, Hodgson, Mourinho, three people who's combined age nears 200 years, are having problem interacting with a teenagers? Well there's a shocker.
