The conclusion of this article(with which I agree)
As a rising tide raises all ships, increased adoption of digital currencies benefits Bitcoin. When users of central bank digital currencies tire of their limited functionality, lack of privacy, and susceptibility to censorship, they’ll come searching for an alternative means of sending money cheaply, quickly and permissonlessly and they’ll find Bitcoin.
contradicts its title imo. According to thefreedictionary
If you describe someone or something as a Trojan horse, you mean that they seem good or useful, but are really there to help something be harmed or destroyed in the future.
English is not my native language, so I may be wrong here, but I think that when people read "Central Bank Digital Currencies Are a Trojan Horse for Bitcoin" they perceive it as CBDCs can destroy Bitcoin in the future, while the article meant to say exactly the opposite.
