The central fact of Tibetan culture today is the split between Tibetans in exile, led by the official government in exile in Dharamsala, and Tibetans inside China, some of whom support Chinese administration and some don't. The article as it stands pretends that this split does not exist, which is exactly the position of the Chinese government.  That's merely the beginning of the POV slanting here.  In terms of literature specifically, the article waves its hand vaguely at many centuries of Tibetan literature, then focuses heavily on a contemporary literary organization established by the Chinese government.  Even the literary cliques identified use standard Chinese naming "the 4 blanks", "the 3 blanks."

Most striking is the complete absence of any mention of the Tibetan government in exile in Dharamsala, India, which has a literary office and a significant library.  There are many books of poetry, songs and stories by Dalai Lamas through history; none are represented here.
