Who gives a shit? Well, for starters, all those who suspected him since always of doping and of ATP looking the other way. Now that he actually admitted to using meth, who is to know what else did he use and got away with it. Dopers are notorious liars.
As to giving back titles and monies, it was Safin basically saying Andre is faking this whole psychobabble thing of taking the burden of lies from his shoulders after 12 years. He cannot be punished anymore, so he can calmly proceed with attention seeking and money grab.
