Regarding Morgan Wallen, my thought was that Music Row and the associated parties have let him back in for future releases and promotion. As you said, he has a tour at Livenation/Ticketmaster venues. he's been back on country radio for a few months to some extent. It's just really difficult spot for something like the Grammy's as it's, in my view, impossible to separate out "Dangerous" as an album from the (in my view justified) outrage of his use of a racial slur. The album release was sandwiched by his SNL delay due to flaunting COVID protocols in peak pandemic season and his video of the slur.
I'm going to guess that if he puts out a new album it'll be in the rotation as it would have been before.
In terms of the fans backing him...well fans back a lot of things that the industry on the whole shouldn't necessarily support. Louis C.K. still sells out tours. DaBaby has a concert tour coming up that will sell tickets. Donald Trump as a human being.
