While most screen reader users have some vision, screen reader software is mostly not affected by styling changes so they will still say "link" when there is one. People with various kinds of low vision (or color blindness) who do not use a screen reader but use text enlargement, screen zooming, etc. would have a particularly hard time differentiating the links from the surrounding text.
