I've never liked Hardwick, full stop. The shitty things he's done, or been accused of doing, are an additional reason to not like him, but I didn't like him to begin with, so that really doesn't change much, for me.
So, I'm not taking his "side" here and I'm not saying that I'll be buying BL3 because I think Schlooters in general are boring and not my cup of tea at all, so it's not a game that interests me to begin with; BUT I will say that if I found out personal information above EVERY person who works on ANY game that I've ever played, I can guarantee you there is at least one horrible person in that group who has done morally reprehensible things (and likely way more than one person). As such, I try not to let the actions of one or two people who happen to be part of a large organization making a game, or a movie, or building a bridge, determine whether or not I will buy, or watch, or engage with that thing.
Now it's a different thing if when doing some morally reprehensible thing they are doing it in the name of the studio, or acting as representatives of said game (see THQ Nordiq for example). In those situations, where leaders of the company are being horrible people in a public-facing manner and not held responsible for their actions, I absolutely understand boycotting the game and/or company. I don't feel like that is the case with BL3....again...not my type of game, Pitchford and Hardwick are not my type of people, but the things they do in their personal lives don't really impact my decision to buy a game or not as per my reasons laid out above.
