Note to mods: I didn't put this in the Amazon forum because even though Amazon is the focus right now, this could affect lots of other companies, the affiliate marketing industry in general as well as affiliates from other states, not just New York. Watch this lawsuit as the results could have far reaching affects on the affiliate marketing industry, on a number of levels. If New York wins the battle with Amazon and is allowed to change the law regarding tax nexus, other states are sure to follow! Companies won't suffer the revenue loss and jump through these extra loops, they will just ban affiliates from states that adopt this law. See especially comments in Orange from the NewsDay article.
