The whole issue with this is complete B.S. and the worst kind of B.S. it's "Apple B.S."
Apple if you are so concerned about security then why do you not brick an iPhone that connects to an insecure public WiFi? I will guarantee your users have a MUCH higher chance of having their data compromised connecting to a public insecure WiFi network than having a fingerprint scanner replaced.
How about 3rd party USB chargers or airport charging stations? Why don't you brick those phones as well? This magic hacker chip you claim can be installed in a fingerprint scanner could also be installed in a 3rd party USB charger right?
C'mon Apple don't go just half-@$$ed why not go all out?
