Cannot tell if it's sarcasm or not. Obviously everyone who reads the headline assumes it's his current computer, and it had some, uh, consequences. That's why they click. That's what makes it clickbait. Nobody would care otherwise.

(Also, if you are willing to be pointlessly formal, it goes in both directions, since it can be argued that a computer, which belongs to a person, who in the future will become DOGE's software engineer, but hasn't become yet, also formally isn't a "DOGE software engineer’s computer".)
