The post is mostly just a raw "data dump" consisting of selections from four of the earliest English language dictionaries (dated 1604, 1656, 1658, and 1755). In every case it is shown that "Witch" and "Witchcraft" are not defined in terms maleficium, but rather in terms of magical powers in a very general way without direct reference to harmful magic. There are references to the perverse Christian notion that magic is associated with "the Devil, or evil Spirits", but this is not said uniquely of Witchcraft alone, but also of Necromancy. In many other sources from the same period one also finds the Devil (and "evil spirits") associated with Conjurers, Sorcerers, Prophetesses, etc. Also, even when Witchcraft is specifically being associated with evil spirits, as in Philips' General Dictionary of 1656, the actions attributed to Witches are described as "Wonders", and in the same Dictionary, the entry for "Wonders" refers to "the seven Wonders of the World," and there is nothing to indicate an association with maleficium or anything of the sort. Moreover, the word "Witch" is explicitly presented in the sources below as being synonymous with a variety of other words to denote magical practitioners, including especially: "Magician", "Prophetess", "Enchantress", "Wizzard", and "Sorceress" (as well as, although somewhat less directly, with "Conjurer", "Wise Man", "Cunning Man", "Astrologer", and "Diviner").

A Dictionary of the English Language, Samuel Johnson, 1755
Wárlock., Wárluck n.s. [vardlookr, Islandick, a charm; werloʒ, Saxon, an evil spirit. This etymology was communicated by Mr. Wise.] A male witch; a wizzard.
Warlock in Scotland is applied to a man whom the vulgar suppose to be conversant with spirits, as a woman who carries on the same commerce is called a witch: he is supposed to have the invulnerable quality which Dryden mentions, who did not understand the word: "He was no warlock, as the Scots commonly call such men, who they say are iron free or lead free." [From John Dryden's notes on his own translation of Vergil's Aeneid (link), specifically in reference to the fact that Vergil allows his hero to be wounded in battle (in Book XII), thus demonstrating that Aeneas "was no warluck", that is to say, he did not possess "the invulnerable quality" that "in Scotland", according to Johnson, is supposed, by "the vulgar", to be characteristic of both Witches and Warlocks.]
