Not by your definition maybe, but that misses the point made in the article:

The op has inserted a specific word here in braces because this isn't a question of what defines a writer, it's a question of who gets paid to write. By that definition, what defines a writer is not for you to decide, it's decided by the market. And the market, in my experience, is not particularly concerned with quality.
