The source isn't just a bit biased, it's hugely biased. Mad in America has an open editorial viewpoint, which is opposition to "the current drug-based paradigm of care" in psychiatry [1]. It's headed by Robert Whitaker, probably best known for his book Anatomy of an Epidemic that questions the routine use of psychiatric drugs [2].
Of course, that doesn't mean the article is useless or not addressing real phenomena. Antidepressant withdrawal is real, and IME it's something you're more likely to hear about as a horror story from a patient (especially if they tried to stop Effexor cold-turkey) rather than as part of standard descriptions of depression treatment and its risks/shortcomings.
