> For example, a person who likes Black Sabbath, and really technical instrumental metal, probably doesn't like the comparatively simpler slipknot
That's just thinly disguised metal snobbery. Almost all metalheads adore Black Sabbath, because they wrote fantastic songs. Sabbath's music caught on because it's so accessible. They were certainly good musicians, but by no means anywhere near the top of the Technical Sophistication Food Chain.
I myself am a cretin, and thus have little patience for technically advanced music, but I'm happy to accommodate a vast world of music where everyone finds something they like, so I'm not going to denigrate anybody's favorite Super Technical Metal Band with twin guitar solos and the 75-piece drum kit - it's all good to somebody. But you've gotta be kidding if you think Sabbath is that kind of act.

I think you might have misunderstood the parent a bit. They're not saying Black Sabbath is really technical instrumental metal but that someone who listens to Black Sabbath AND ALSO likes really technical instrumental, is probably not looking to listen to Slipknot (though I suppose that could depend on the technical to Black Sabbath ratio).
The point is more that Spotify supposedly recommends without taking into account what people actually listen to. Spotify says "oh this person listens to Black Sabbath which is a popular metal band. They also listen to a lot of Blotted Science, which is also a metal band. They most likely will like Slipknot, another popular metal band" instead of "This person listens to Black Sabbath and Blotted Science. People who listen to both Black Sabbath and Blotted Science also listen to Nile, so this person will most likely like Nile"[0].
[0] Blotted Science and Nile are the only technicalish bands I know off the top of my head. If those bands don't work, try Blind Guardian and Stormkeep
This implies that, if there are many different subgenres with little overlap in audience but they all agree on Black Sabbath (and little else), drawing conclusions from "listens to Black Sabbath" is doomed to fail. "Listens to Black Sabbath" simply isn't particularly specific, and those subgenre-heads are all about specifity. Same as that you can draw a lot more conclusions from "likes listening to Number Nine" than from "likes listening to Yesterday"
