That's just because getting you to buy it is more important than having you enjoy it.

only serves to make something pretty in an ad.

A photographer I know mixed a different beer in, when the one he was supposed to photograph didn't foam properly.
He also sprayed on the condensation so he didn't have to lug around a camping fridge

I have spoken with some of the people involved with this research previously. Beer foams aren’t really the focus here, more that it’s a complex system useful for developing the technique. Interfacial rheology and film drainage have a lot of applications. For example, this research could assist in the development of vaccine delivery methods (what should you coat the inside of your syringes with or what surfactants should you add to the vaccine to make it flow in a way that doesn’t damage the proteins or form bubbles). However, a lot of these vaccines may be difficult or expensive to prepare while beer is (relatively) cheap and readily available. Also, since the specific system doesn’t matter, why not have a little fun and use beer.

Soaps, detergents, firefighting foams, and paints might also benefit from this research.

Yeah I don't want this... It's like when people show off how stringy the cheese is on their pizza or grilled cheese. I hate that and feel like I'm taking crazy pills when it's portrayed as a good thing.

Research shifted significantly away from thighs in the late seventies. Two seminal works (fat bottom girls in 1978 and baby got back in 1992) have kept researchers focused on posterior assets for decades.

I can see where you're coming foam, but no
