How is it a poor equivalency? https://amazon is an attempt at just entering the tld without anything else and https://com is entering the tld without anything else. Just because https://amazon.com exists, doesn't mean "amazon" in and of itself means anything in the grand scheme of things.
And my point was that com alone would lead nowhere reasonable (aside from the Verisign NIC page), but Amazon by itself could very well lead to amazon's webpage.
