@Leonabcd123 Thanks for opening a PR! I will look into this and find out whether it matters to us either way, because if it doesn't, no reason not to just accept the change.

@Leonabcd123 Our team has reviewed this. We agree that this passage is problematic; we shouldn’t be referencing a Wikipedia article that contradicts something we’ve said in the text. However, we also slightly lazily refer to “Unix systems” in the same passage and, for example, the Apple documentation still refers to superuser do . As such, on review, we’ve concluded the best thing to do is actually to delete the passage: it doesn’t add any real value to the reader and could be potentially confusing. If you’d like to alter your PR accordingly, we’d be happy to approve and merge it, giving you attribution for the change. Thank you!
