Your points are well intended but irrelevant to the article. This is a breakthrough for plastic bottles that has the effect of reducing company cost and environment impact; even if the company agreed with your points, following them would lead to a bankruptcy.

I have not yet read the article, but I initially understood that the thickness of the bottles, and thus plastic used, has decreased. This would be a win for use-and-trash water bottles like for restaurants or tourist spots, because it would reduce pricing and pollution.
