Re: Nothing new...
You mean Facebook, that company that saw its userbase growth slow down markedly and saw its stock drop by over a third after all the scandals? It seems that at least some people care.
Also - Facebook's primary product is selling data about you. Amazon's primary product is selling stuff to you. There's less of a network effect and more alternatives in the latter, and as others have remarked - outright snooping in your homes is a tad worse than Facebook figuring out what you do and showing you ads in response. I use iPhones over Android for the same reason - I'm more the customer and less the product.
I guess everybody makes their own decisions in this area. It's a fine balance between trying to protect your privacy and enjoying some of the advantages of the modern age. YMMV, etc.
