I've never disliked David Ortiz. He's always been an affable personality that was hard to hate. Don't get me wrong, I hated the player for what he did to my Yankees on a regular basis, but never had anything bad to say about the person.
The disclosure of a failed 2003 drug test didn't change that, but the scales are starting to tip in the other direction. According to this article in the Boston Globe, Ortiz was notified in 2004 that he had failed the survey drug test, making Ortiz's claim that he was "blindsided" by the revelation total bullsh-t.
Granted, he may not have been told in 2004 what he tested positive for, so I understand him wanting to find out before addressing the media, but as time goes on and the silence continues, he looks worse and worse.
