I might arrive a bit late to the party, but I don’t feel an aesthetic is necessarily tied to an ideology or a way of thinking. You can see that with solarpunk aesthetic (greenery, livability and all that sort of stuff) os used by totalitarian regimes and capitalist companies.
Although it is true some aesthetics and styles always carry the nostalgia of their previous uses, as is happening in your case, I think claiming, reclaiming or simply broadening the use of a specific style is accomplishable and not unheard of. In that spirit, I would suggest we keep using them and tweaking the topics shown to move away from a possible corporativist/capitalist reading and make the message of sostenibility more clear.
Wether this type of artistic approach shows a remotely realistic future and if this mught pose a problem, and wether companies making green efforts carries more problem than benefits, are both topics worth thinking about; I feel this play also an importan role in the way you feel towards Frutiger Aero.
I always found Park Güell to be an outstanding proof of concept of organic architecture, specially since it was thought as a housing complex. It’s true that it’s quite extravagant, but the design ideas regarding space, light and ventilation behind it are very interesting to say the least.
