Anyone serious about crypotcurrencies will know at least know two ideas not being Satoshi originals - 1. Ecash, Digicash - author's refer to it in paragraph one as something people are aware of. 2. PoW/Hashcash - Sure people might not be aware of the anti-spam but they are aware of Hashcash and Adam Back. That being the case, I think author's assumption that everyone in the bitcoin space thinks Satoshi as the one inventing everything and hence the article needs to prove otherwise is..well false at best.
