For the record, I did not return my (4x cheaper) iPad. I didn’t ever buy a Vision Pro. Because of the Apple ID issue. I’m trying to convince Apple that they should care because they lost a sale.
Also, they've probably done the maths and knowing their "loyal" customer base people would be more than happy to pay for multiple redundant devices just to have them seamlessly work together. They are in business of selling premium devices to people who have low sensitivity to price and cost
