Amazon refuses to even sell Chromecasts or Apple TVs and lies about it if you contact customer support. I've been told that "it's just out of stock", that "we had too many complaints", and even "Apple refuses to let us sell those products".

It's why I canceled Amazon Prime (Funny, after being a customer for over a decade, with Prime since it was offered, cancelling was a single click, with zero follow-up or attempt at retention. Not even a "Oh, hey, why did you decide to cancel after so many years?")

This is correct. I have google music and my echo won't play it. Really annoying.
