I don't think it has anything to do with the media. I think it's more an issue of not wanting to be around other baseball players. Remember, he just gave a bunch of names of users to the feds - some of which may be current teammates. Even if he didn't name any teammates, I would imagine there are probably some guys who'd be pissed that he ratted on fellow players. I'd imagine that getting caught with HGH is an offense that could get him sent to jail, and his options were prison, or cooperate and tell what he knows. That's true too...but in any case, it was a way to run and hide.
