Why use citation when hyperlinks exists?
To me, hyperlinks seem superior in every way.
I would guess the main reason is that links are not stable?
If one sentence from another article is relevant, it seems better to copy the sentence (and add a link to the context) than expect the reader to find the relevant sentence for themselves.
