I don't want to go into the debate if he was a good human being or not. Because I honestly don't want to say any controversial stuff about a dead guy. And obviously, he was closely related to Rajasthan Royals so he will obviously have good relations with Indian players and the Indian board. all I want to say is he was a great player and certainly the best leg spin bowler.
And yes Muttiah Muralitharan was a better bowler than him and at that time the Sri Lankan off-spinner was also facing a lot of problems from certain an instead of being not guilty. But the impact that Shane Warne had cannot be neglected at all.
You are right now it's all end, and we don't need to talk about this all but one thing is clear after retirement he was doing many things and these all just for his business so just because of this mostly he has done many wrong things as well because he needs some good intention in media, so his tricks were working for him, and mostly he was talk of community about his behavior and good relationship with Indian players were their necessity because after introduction of IPL India is the biggest market for this game and everyone wants to take his share from this.
He was also shareholder in Rajasthan Royals just because of this all good relationship with Indian players was very important for him. Specially after IPL many Australian and New Zealand players were having good things in India, so they are doing this all for their own sack.
