In poor taste? Oh... you know... probably, especially once you consider that Del La Hoya, who is Canelo Alvarez's fight promoter, literally just went back into rehab a day before Mayweather Jr's fight with Alvarez. But Money is going to be Money, and winning with even a shred of class or not kicking a man while he is down doesn't seem like something he's interested in. On the other hand, De La Hoya could have not become addicted to drugs in the first place. So there's that.
