Fortunately, Mr. Hughes had taken a backup, so he overwrote the latest firmware at hand and restored it. I asked a question for Twitter account of Eiron Mask CEO and Tesla Motors as follows.
So,#TeslaI try them to retaliate by remotely commanding my car to downgrade to 2.12.45. I cut them off.@ Elonmusk@TeslaMotorsA word?

The mask CEO's answer to this was a word that "good hacking is a gift" after denying its own involvement in downgrading.
@ Wk 057@TeslaMotorsGood hacking is a gift.

Even after the summer of 2015 aloneJeep Cherokee,GM,Corvette,Nissan · LEAF, "Vulnerability" that accepts operation from the outside in various cars has been found and it is natural that manufacturers can update the firmware of each vehicle in order to respond to it In the future it may be that the "initiative" fight between cars occurs between the user and the manufacturer.
