You're absolutely right, Amazon did commit fraud by not confirming that the person doing the ordering is the owner of the account. They should be held liable for the result.
What? I'd be willing to bet the T&Cs have a section along the lines of "Amazon is not liable for accidental purchases made by the user, minors, exceptionally realistic sounding parrots, or other unauthorized persons that are in the presence of the device with the permission of the owner."
In other words, when you stick an automated device in your home and give it permission to spend your money, you should probably exercise a bit of caution operating it. In the same way, credit card companies are not charged with fraud when little Timmy uses his Mother's Visa card to buy a few hundredweight of gobstoppers...
My friend's name is Alexis, we basically turn off Alexa when she's over. Now, what if Alexis is helping me pick out a doll house for my daughter and I say Alexis, Order me a dollhouse?
Now let's say this is a biopic that happens to be playing on your TV? All true events, and if you enabled purchasing directly from your Echo without safeguards you'll get an attempt to purchase a dollhouse. None of this is fraud, none of this is intentional. These are all shortcomings with where we're at.
Now if I ran an advertisement that said "Alexa, order me a SuperafunTime My Brand Dollhouse"- I should be slapped with whatever the law allows.
