Put me in the hate this bucket as well. A ticket stub is a cheap collectible and way to remember you were at a big game. No one is screenshotting their ticket after a buzzer beater to show their friends 10 years later that "I was there"...
Hopefully they don't go the Ticketmaster route where you can't even use a screenshot to get in anymore. Ticketmaster now makes it so their digital barcodes constantly update so a screenshot from 5 minutes ago is different than what's on your phone right now. It's the dumbest concept yet, especially in older buildings with terrible signals or large stadiums where cell signals get overwhelmed since we're certainly not at a place yet where all stadiums and arenas have strong wifi signals, especially in lobbies or outside the doors.
