Magnussen's own Saudi Arabian Grand Prix was ruined by incurring an initial 10-second penalty for contact with Alex Albon in the Williams.
His focus then shifted to holding up others so team-mate Nico Hulkenberg, who hadn't stopped under an early safety car, could pull out a gap and claim 10th. Crucial to that strategy was overtaking the RB of Yuki Tsunoda on lap 17, which Magnussen did by leaving the track.
Instead of giving the position back to Tsunoda, Magnussen opted to cop an additional, largely irrelevant 10-second penalty, which allowed him to keep blocking his rivals so Hulkenberg could pit and come out ahead of him and secure a valuable point.
RB slammed the move as "unsportsmanlike" and said it would raise the issue with the FIA.
For this season the FIA had already increased the penalty for this gaining an advantage while leaving the track from five to 10 seconds to deter drivers from choosing to get penalised in a bid to gain track position.
And while it technically worked for Magnussen, whose own race was wrecked, that didn't stop him from aiding his team-mate.
Haas chief Komatsu accepted that Magnussen "should have just given the place back" and tried to get past the Japanese driver again, which he believes the Dane had the pace for.
"I believe at that point in the race, if I remember the projection very well, we are fighting with Tsunoda for P10," Komatsu said.
