What's up with so many utopia/solarpunk art being Frutiger Aero?

Frutiger Aero is a Corporate style. A Capitalist style in some way.

For me, Solarpunk is an anti-capitalist aesthetic. I've read very often it's related to Art Noveau, Expressionism and Eco-Aesthetics, but I am new to Solarpunk, so ofc it's not knowledge, but just my view.

But aren't artworks that use this aesthetic actually non-Solarpunk then? And if they are, why are they? Why are there so many that see a blunt ugly concrete world with some plants on top as something good, when you can have a beautiful world with plants on top?
