He certainly shared with Turing the respect of others in "the trade". He also shared with him the dubious honour of being hounded and persecuted by the post war establishment. Not perhaps to the extent that Turing was driven to take his life, but nonetheless getting a despicable letter disowning and dishonouring him by the head of GCHQ, and being ostracised from the Intelligence community.
He was essentially a whistle-blower, claiming that we were making exactly the same mistakes that the Germans had made in the war, hence compromising our security.
The problems at the end lay, it would seem, in a combination of the genius of his early years coming into conflict with the principles and possibly naivety of his later years. His war work was so far ahead of its time that the techniques he developed were still in use in the 1970s and 80s - and I believe derivatives of Enigma were still being used, including by the US and Russia. However, by this stage, he was out of the spying business and had no knowledge of what was going on, so to unilaterally go public did create a bit of a problem for the authorities who were still reliant on his techniques - as Sir John Scarlett described.
Could things have been handled differently, more discreetly - by both sides? Probably. If he genuinely believed that the same mistakes that cost the Germans dear in the 1940s were being repeated in later years, there were probably better ways to flag that up in the first instance than in a book freely available to all, including our enemies at the time.
