I see you modified that question, well done.
I thought it was quite a good survey.
I once designed a bottle, with a shape optimized to fit in the hand. The shape was very nice for its size.
Then the client wanted the bottle to contain significantly more and we couldn’t just uniformly scale it up because of the ergonomics.
We also couldn’t go back to revising the design since a lot of money and time were already invested, so it became a bottle that lost a lot of its original aesthetic appeal. I think that is unethical as well since there was no good balance of beauty, profitability and usability.
I also worked on projects where a lot of plastic was used to add only a marginal amount of value to the brand, so now I am much more conscious of minimizing material consumption.
