Why is Tiffany doing this to herself?

Literally nothing here is saying what she actually say

Her whole comment was saying about how in the past there was only one camera filming the entire stage so the girls had to be at their best even when they were in the back of the stage to still stand out in comparison of the center to be notice

But when she went to do the 15years anniversary promo they learn about fancam

And that's why she thought new idols are more lax in trying to stand out in the back of the center

Because now they have their own fancam who gets uploaded to internet

So they don't have to be as "hyper" than they used to be to stand out in the group performance when they are in the back or when it's not their part
