That would make me a hypocrite, but it wouldn't make me wrong. Pointing out hypocrisy to 'dunk on' people is rarely a persuasive rebuttal.
In your example, you're drinking yourself to death despite knowing it's stupid, and probably despite others telling you not to. Why would you think lecturing your friend helps?
Your reaction should be, "hey, what would stop me from drinking? Maybe I should try that and propose it for my friend too?"
In the NYT example, they should know why they're using the dark patterns, and what would get them to stop, and should be proposing that.
