Why is logistic equation called “logistic”?
The logistic function solves the logistic ODE which is the continuous version of the logistic map.
However, I was not able to find why any of these things are called "logistic".

Doesn't the first link you supply answer the question? "A logistic function or logistic curve is a common sigmoid function, given its name in 1844 or 1845 by Pierre François Verhulst who studied it in relation to population growth."

The term is very old, and has been used, for example, to mean arithmetic. Verhulst introduced the term for the curve that is often used to model constrained growth. I believe it is not known why.

@EuYu The fact that the name was "given by Verhulst" does not explain why it was given. Usually people pick names for a reason, but maybe Verhulst was an exception.

From what I can tell, Verhulst wrote in French. I'm guessing that "logistic" here comes from logistique in French which in turn derives from "to lodge" or "to house". The curve originally arose from the study of population growths so this seems like a reasonable interpretation to me. I would probably ask a linguist to be sure.

Ok, I looked at the French wikipedia, which states "Le nom de courbe logistique leur a été donné par Verhulst sans que l'on sache exactement pourquoi." - "The name "logistic curve" was given to it by Verhulst, but no one knows exactly why". The reference $href=rasch.org/rmt/rmt64k.htm$ gives the following commentary:

The Rasch reference (by John M. Linacre) confuses several loosely related words. The connection with logarithm is speculative; they're both from λόγος (lógos), but λογιστικός (logistikós) was an Ancient Greek word, while logarithm was a modern coinage. Also, logistics (logistique) was an 1830 French military term, derived from logis (lodgings), and presumably unrelated (a mathematician would more likely draw from Greek mathematical terms, rather than new military terms).

Nous donnerons le nom de logistique à la courbe

He does not explain why he uses this term, but it is presumably by analogy with arithmetic and geometric, and in contrast to logarithmic, as in figure below (from the original paper).
The French term logistique is from Ancient Greek λογιστικός (logistikós, “practiced in arithmetic; rational”), from λογίζομαι (logízomai, “I reason, I calculate”), from λόγος (lógos, “reason, computation”), whence English logos, logic, logarithm, etc. In Ancient Greek mathematics, logistikós was a division of mathematics: practical computation and accounting, in contrast to ἀριθμητική (arithmētikḗ), the theoretical or philosophical study of numbers. Confusingly, today we call practical computation arithmetic, and don't use logistic to refer to computation.
Verhulst first discusses the arithmetic growth and geometric growth models, referring to arithmetic progression and geometric progression, and calling the geometric growth curve a logarithmic curve (confusingly, the modern term is instead exponential curve, which is the inverse), then follows with his new model of "logistic" growth, which is presumably named by analogy, after a traditional division of mathematics, and in contrast to the logarithmic curve. The term logarithm is itself derived as log-arithm, from Ancient Greek λόγος (lógos) and ἀριθμός (arithmós), the sources respectively of logistic and arithmetic.
There is no connection with logistics (1830), which is instead from logis (lodging), and was military jargon.

We will give the name logistic to the curve
He does not explain why he uses this term, but it is presumably by analogy with arithmetic and geometric, and in contrast to logarithmic, as in figure below (from the original paper).
The French term logistique is from Ancient Greek λογιστικός (logistikós, “practiced in arithmetic; rational”), from λογίζομαι (logízomai, “I reason, I calculate”), from λόγος (lógos, “reason, computation”), whence English logos, logic, logarithm, etc. In Ancient Greek mathematics, logistikós was a division of mathematics: practical computation and accounting, in contrast to ἀριθμητική (arithmētikḗ), the theoretical or philosophical study of numbers. Confusingly, today we call practical computation arithmetic, and don't use logistic to refer to computation.
Verhulst first discusses the arithmetic growth and geometric growth models, referring to arithmetic progression and geometric progression, and calling the geometric growth curve a logarithmic curve (confusingly, the modern term is instead exponential curve, which is the inverse), then follows with his new model of "logistic" growth, which is presumably named by analogy, after a traditional division of mathematics, and in contrast to the logarithmic curve. The term logarithm is itself derived as log-arithm, from Ancient Greek λόγος (lógos) and ἀριθμός (arithmós), the sources respectively of logistic and arithmetic.
There is no connection with logistics (1830), which is instead from logis (lodging), and was military jargon.

(Cross-posted from History of Science and Mathematics: source of “logistic growth”?)
As stated above, the term logistic is due to the Belgian mathematician Pierre François Verhulst, who invented the logistic growth model, and named it logistic (French: logistique) in his 1845 "Recherches mathématiques sur la loi d'accroissement de la population", p. 8:
Nous donnerons le nom de logistique à la courbe

Doesn't the first link you supply answer the question? "A logistic function or logistic curve is a common sigmoid function, given its name in 1844 or 1845 by Pierre François Verhulst who studied it in relation to population growth."

The term is very old, and has been used, for example, to mean arithmetic. Verhulst introduced the term for the curve that is often used to model constrained growth. I believe it is not known why.

@EuYu The fact that the name was "given by Verhulst" does not explain why it was given. Usually people pick names for a reason, but maybe Verhulst was an exception.

From what I can tell, Verhulst wrote in French. I'm guessing that "logistic" here comes from logistique in French which in turn derives from "to lodge" or "to house". The curve originally arose from the study of population growths so this seems like a reasonable interpretation to me. I would probably ask a linguist to be sure.

Ok, I looked at the French wikipedia, which states "Le nom de courbe logistique leur a été donné par Verhulst sans que l'on sache exactement pourquoi." - "The name "logistic curve" was given to it by Verhulst, but no one knows exactly why". The reference $href=rasch.org/rmt/rmt64k.htm$ gives the following commentary:
