I'm really confused by people (well, not so much after the elections in USA).
Why would you keep supporting some con artist, who swindled millions of people? What's the appeal of convicted fraudster? He is a great salesman, I give him that, but aside from playing tricks on you, there is nothing good or useful about his ''work''. He brings only harm and damage. Man like this might be good for entertainment, but way too many people take him seriously.
As for this particular book, it consists of well-known mnemonic techniques, given with a great aplomb. There is nothing new or remotely original here. If you are a beginner in reading memoria technica, you will enjoy learning those little helpful tricks (please, do not expect too much!). But for those of us, who have been reading on this subject for a while, there is nothing remotely interesting.
