The top 8 players in the tournament get invited to the next tournament. Hans Niemann got a free point from the game Carlsen resigned. That impacts the standings for all the other players. It’s hard to see how they’re not impacted.
In addition to that one, very concrete impact, the situation may also have subtle effects. Players may be going into matches against Hans being down a point when they would have been tied, changing the psychology of their play style. Similarly, Hans may play more confidently being up a point. Even spending a single second thinking about the situation is an unnecessary impact forced on the other players by Magnus. Pretty unsportsmanlike.
