This is a losing battle, as I know a little something about the subject. I 
suspect they're actually using encrypted communication channel, and dealers 
have the key. While they probably are not making the algorithm widely known 
that is not actually what they're protecting. They are protecting the keys 
for the encryption.   The hackers are probably finding a way around the 
encryption, or they have simply cracked it with brute force.  This is 
defensible by John Deere, and I believe that hackers will lose.

It should be noted that as a practice  algorithms are easy to file as a 
copyright or patent, but are hard to defend.  See Alice vs CLS Bank.

Consumers and John Deere will remain locked in battle for years.  In the end 
I suspect consumers will lose.

Another reason to use antique tractors :-)
