Why doesn’t online cash games do deep stack poker?

So I am watching Live at the Bike, and everyone had like 200-2000bb. And deep stack like this really seems to make the game a lot more interesting because there is a ton of implied value.

Turn and river decision matters a lot more.

But on line 100BB by the time river comes around it matters a lot less, stack to pot ratio is already 2-1 or 1 to 1.
