We’re not quite saying the same thing though because …
It’s not a 2 vs 3 issue. You can have an infinite number of instances of the same logic and it still not be a case for generalization because it’s not actually general … it’s just an infinitely large program. You can also have two copies of the same code that should be reduced because they are general (e.g. you have the exact same algorithm for generating a UUID copied into two different spots). If you’re thinking about it in terms of quantity you’re already doing it wrong.

It’s not fixable by “just” copying something.
Those two points are really important points.
You’re ignoring that simple principles make great guidelines for not overthinking things.
And you’re doing so in the context of an article about the dangers of overthinking things.
You’ve over thought an article about the dangers of overthinking, while alienating potential collaborators with a condescending tone.
You’re coming across like one of the rookies who need this warning.
Consider counting to three, before applying DRY. It works.
