At $3 a ticket, Jim Morrison got away with being an egotistical a$$hole. At $15 a ticket, Axl Rose got away with it as well. Neither were political but were repulsive.
Waters, with the help of his bandmates, wrote some classic songs that sold millions of albums, until his ego and a$$holism caused the band to dissolve, eventually continuing without him. Even though the band then made less than classic albums, when they toured at the same time he did, the audiences voted with their wallets and attended the Floyd shows en masse instead of his.
At $100 + a ticket, as his art has declined and his attitude is insufferable, don't be surprised if this is his last tour. His behavior is overly political as well as repulsive.
