There are simply too many inconsistencies in the ban. With the thrones of these high lamas like Trijang Rinpoche, ex Gaden Trisur, still remain intact in Gaden Shartse's prayer hall, it is already telling to everyone that there is something not right about the ban.
On top of that, TGIE keeps very low profile and quiet about these, and the reason is quite obvious. They know the world is not interested in them or in Tibet, but only in the lineage masters who uphold the the Gelug Traditions. Right now, TGIE basically has no country to govern, and as HH Dalai Lama has already made clear to withdraw his political power in TGIE, they could not afford to have any bad publicity on TGIE, as any announcements concerning for example removing the thrones of these high lamas from Gaden monastery will further split the Tibetan community, which is what the newly elected Prime minister Lobsang Sangay trying to avoid.
I think this is the best what TGIE have done so far, by remaining silence about the DS ban and they should. And I hope, under the new leadership of Lobsang Sangay, they are working on ways to re-unite the much divided Tibetan community.
