I agree with this - there is historical value in the messages, which helps build a picture of events during the war.
Using useful hill climbing algorithm (mixed with brute force method, BTW)
If you look at it that way, every method is brute force. I consider a brute force decryption to be a full search of the key space, not a guided search that cleverly skips irrelevant parts.
I fully agree with this.
In the article you talked about usefulness and I did not agree with the argument. Being an interesting from historical point of view and useful is two different things.
