I didn't realize anything. Everyone and their mother has been saying that about Satoshi since day one... Also, Adam would have infinitely more to gain from being Satoshi than from Satoshi remaining unknown. He's been trying to take credit for Bitcoin ever since he realized that Bitcoin was actually worth something (he initially dismissed it). All his actions point to someone who's largely motivated by financial gain whereas Satoshi hasn't touched a single of his 1M+ BTC.

If you're interested in serious research about Satoshi's identity, try this paper instead: https://arxiv.org/abs/2206.10257

As per the quotes, it could've been that he had read them, liked them and kept repeating them. However given other matching circumstances such as grammar this becomes unlikely. Also, this is just a single journalist; to know precisely this should be outsourced to a company doing forensics.
