All the letters from the highest authorities and also from others are a form of unity from all the Lord Shugden lamas and practitioners that in one voice acknowledge the benefit of dorjeshugden.com and these also shows that Lord Shugden practitioners are not minority. We are all over the world and this is how the practice of the enlightened being grow and the CTA should stop harm the practitioners and the Dalai Lama should quickly lift the ban as there is no point to separate the Buddha dharma practice which only causes harm to the practitioners.Those letters are from the erudite masters, are from the lineage masters that took rebirth to come back and continue their previous lives mission to keep benefiting others, the lineage holder and this is how strong their voice are.
I believe the letters is not to show disharmony but is more to show the righteous, the beneficial contribution from the website which keep showing the truth and pure lineage teaching of Lama Tsongkhapa teaching and Lord Shugden practice.
