In my opinion, John Mcafee is interested in gaining publicity and attracting people to his post to make himself more popular and possibly give him a sense of humour. There have been several allegations as regards who is Satoshi Nakamoto and non has yielded anything fruitful.
You may be right there, Like the quote "the more you hate the more you love" He's doing it for him to gain bashers from crypto community while he is gaining popularity because of his unprofessional words especially in the twitter. Satoshi Nakamoto is totally uknown many knew it he, have no identity only some of the possible footprints on his post under his name in the past.
