>but I have liked the idea of the dark magic being some sort of alicorn mgaic
In terms of Alicorn and dark magic being linked, I generally have come to see that as being Unicorn magic specifically, because most of the magic we see Alicorns using is unicorn magic - but perhaps since we see both light beams and the Sombra-esque dark magic being used by Alicorns, perhaps it's that they're tapping into the elements of harmony and disharmony. I guess I can't say for sure that the elements of harmony are diametrically opposed to dark magic, but it seems as though the show portrays it that way. Interestingly, neither Discord nor Tirek seem to tap into the same dark magic, animation-wise, that both Sombra and Twilight show the ability to use. Tirek fundamentally uses the powers of others, and Discord actually seems to fundamentally use the same magic as Pinkie - he doesn't really use his with a glow like unicorns or with the same effects Sombra's magic has, so I'd actually posit that Discord is a powerful user of the harmony magic the Earth ponies are able to tap into, and that it's simply his chaotic nature that allows him to use it so effectively, NOT that he actually uses any kind of 'chaos magic' directly. If the magic of the world runs along a different axis of harmony compared to material objects, I could see it being fairly 'random' to common sense to know in what manner things are connected. In this sense, the two 'paths' are either going with that nonsensical-seeming flow, as Pinkie and Discord do, or using a power from within to force and bend magic into the shape you need it to be. I'd then suggest that unicorn magic sits in a balance, where you have to allow your own inner power to work with the magic of the world to a certain extent, so that you don't go into the extreme where dark magic lies, where it's fundamentally perverting and twisting reality into doing what you want such that it violates it's harmony. As with all these things it needs more thinking on my part, but the thing which does seem quite clear to me from thinking about this is that, contrary to what you'd assume, the cosmological constants at work in this universe aren't especially directly present in the story. You'd assume that Celestia is the demigoddess of the 'good' axis and somebody like Tirek the 'bad', but as I went over, only Sombra out of the villains seems to directly tap into dark magic proper, and Celestia and Luna and the other Alicorns are ultimately just powerful ponies, with the real source of the opposing axis to dark magic being Harmony, which starts as disparate elements in the pilot and gradually grows in power along with the mane six throughout the course of the story. I don't even know if I'm characterising disharmony as relating to dark magic and the windigos correctly, necessarily. But I do find it interesting to hypothesise that all the events of the show are essentially the modern backdrop to a far older conflict between fluctuating forces of harmony and disharmony.

Also another reason I link unicorn magic moreso to disharmony is EqG, where magic outside of it's proper place consistently causes evil results, but that's sort of the reason for my personal view - whether EqG is canon to how we interpret Equestria is a whole other question.
