If PepsiCo (one of the companies listed) ceased production of plastic bottles immediately I would be happy. That is a serious, credible commitment to improve.
We don't have to ban them, but we definitely don't have to support and laud them either. Tolerate and shame, like we do with tobacco companies, seems like a reasonable approach.
And to disclose my own biases, I'm 100% on team "Full Sugar Soda" and will definitely choose no soda over sugar free soda every time.
