Business Ethics debate help

I have a group debate, topic is It is ethically permissible for Amazon to develop and open automated grocery stores.  and I am CON side.

I  am focusing onPrivacy (selling information), basd on this way, I need help do some research, and make powerpoint, also write something to show it is not good for Amazon to open automated grocery stores. As strong as possible.

If you dont know about amazon automated grcery stores, google "amazon go", or watch this video https://www.youtube.com/watch?v=NrmMk1Myrxc
