Knock on wood, but given where we are in 2023, no one really expects Evenepoel's situation to be life-threatening, and it's early enough in the race that it doesn't feel like whoever wears it stole it from him. And I doubt he cares in the slightest if someone else wears the jersey tomorrow.
If Thomas had lost the stage by three seconds and the jersey had gone to Roglic, then maybe would it be a different story, and Primoz might at least try to decline wearing it for a day out of some sense of respect for Remco's misfortune. But given Thomas' career arc, his relationship with the Giro, and the fact that Ganna just tested positive, I would think most critics would be hard-pressed to muster up the outrage to direct at him for taking advantage of this chance of wearing the maglia rosa. As always, YMMV.
