Yeah, it makes total sense.
I was watching Flossy's unboxing and he compared the Fold 5, Pixel fold and (I think) a Xiaomi fold. When you open them up, it becomes immediately apparent why Samsung builds it's fold the way it does. The pixel hadd MASSIVE bars at the sides of the screen that looked absolutely awful, whereas the Z Fold just looked good. To be honest, and I've tried to keep quiet about it, but anyone buying the Pixel fold just because they like the outer screen is actually cracked.
That said, if the Z FOld had the same aspect ratio as the Pixel fold I'd consider buying one...those ugly black bars (as far as I know) can be fixed by rotating the device 90 degrees.
As an afterthought, I wonder if we will see a lot of Pixel Folds with cracked screens around the 8-12 months mark due to all the time the screen spends folded... and also just because Google is bad at building things haha.
