And while I think the whipped foods are stupid, I don't think that packaged food sellers are necessarily scumbags. They're merely people responding to incentives, just like everyone else. The food market has razor-thin margins and consumers are ill-informed. Neither consumers (who are hard to inform) nor regulators (who are captive to the multinational conglomerates) have been able to push back more strongly than the profit incentive, so the so dark patterns like those you describe are inevitable.
So these whipped products seem pretty useful.
My kids eat a lot of creamcheese sandwiches. Block cream cheese just destroys sliced bread.
The products in that category that have been puffed up with air (and don't meet this minimum) get sold as "dairy desserts".
(I don't work on the food industry, so I won't be shocked if I got details wrong.)

I don't think I'd want to eat that
There is no way i would eat something linke that.
These days the trend seems to be to reduce the packaging, at least here in the UK. "Same size - less packaging!". So it seems like reduced packaging and distribution costs, and perhaps fitting more onto store shelves, outweighs any extra sales from customers who are fooled into thinking the product is bigger than it really is?
Basically take anything homogeneous, add gum, add air, create a foam. Basically like an Aero bar but with way smaller bubbles.
You just cut a quarter (I'm guessing on this figure) off your ice-cream ingredients by weight and you can now advertise "scoops from the freezer"!
It's genius but just a more complex version of putting all the pizza toppings in the little window, or having the coleslaw tub be much wider at the top, or putting everything in a wide plastic skirt so the box is 20% bigger than it needs to be, ... packaged food sellers are scumbags.
