iptables would be looking for (and blocking) the button trying to reach it’s server at Amazon. The arp solution merely looks for the thing trying to get on the network by testing that is has a unique MAC address. Which is fine, but it requires additional software, vs. iptables which is definitely going to be there on a router.
