It seems like Travis Scott is being treated far more harshly than other top names who had concert deaths, Pearl Jam, The Who... those acts continued to perform.
Maybe this will blow over. Maybe the climate has changed in accepting these tragedies, with #metoo. No longer accepting "status quo".
Travis Scott encouraged this type of behavior, that's the difference. It was his whole schtick. He encouraged a kid to jump off a balcony at one of his concerts, and someone ended up paralyzed because of it. That's just one example of the type of performer TS has always been.
