Amazon won't be the only company dropping their MN affiliates, there will be dozens.
Companies don't have to collect sales tax on out-of-state purchases unless they have a physical presence in the state. You (the purchaser) are supposed to pay sales tax due on those purchases when you file your state income taxes. This is true whether you order by phone, by mail order ... or order online.
These laws are using a specific advertising model as a loophole to establish a nexus, in an attempt to proactively collect part of the tax which purchasers are (cough) "forgetting" to pay at tax time.
