Definitely makes you go oof, but I imagine this is an accident. A more damning action would be retweeting and letting the retweet stay up.
Also I'm not in the camp of thinking that likes are not endorsements. I think it is reasonable to question someone's public likes when it further spreads certain views or personalities. Especially when discussing brands or professional Twitter accounts; people know best practices.
I don't endorse this harmful content or this bigoted person, but I wanted to save their tweet for later, while sharing it with my timeline, doesn't fly with a sizable chunk of people.
tl;dr: IGN probably goofed and this probably isn't that deep
