If you come across an Amazon related widget or gadget or some other tool on the Internet which is being made free to use by the author and in the code somewhere is a Subscription ID which one assumes is from the authors AWS account, and then you are given permission to place your own associateID-20 to get credit: 1. what is the possible incentive for an author to provide this code and tool which uses their own Subscription ID while presumably the user would be credited for any commission? 2. does the end user in any way making use of this code which has someone else's Subscription ID go against terms of service of AWS? This is a general question and does not pertain to a specific or particular application. Thanks
