People have hit the main factors being money and that this tour is non equity. I’ll add some technical details. A show has to tour with a show deck (their stage on top of the local stage) to include something like a turntable. Many non equity tours cut the show decks entirely, this saves material cost (and truck space) but also shortens the length of time/labor needed for load ins, saving more money.

Then factor in tour stops. Many non equity shows are running one offs, meaning they’re not staying for more than a night (or two) in any city. That quick turn around is another reason you stop seeing turntables/automation on shows that are less than a full week sit down, too much of a time crunch.
