Bests & Worsts Reviews from Amazon

I was merely trying to get information on this service through our FireTV...but when I clicked on the app, it automatically enrolled me in Amazon Prime (with an ongoing associated charge), CBS All Access (with another ongoing associated charge), as well as other services (e.g., Amazon Unlimited Music) in which I had neither expressed interest nor ordered. At a minimum, Amazon.com should notify the consumer about exactly what is entailed in ANY such seemingly innocent action, such as clicking on a FireTV app, BEFORE activating an associated account which carries a financial commitment.
