As SabS said, it is a business decision for Apple to make stands that benefit them financially. But then again they had to toes certain lines for their users. They have to balance a giant.
As for the CTA, they know the writing is on the wall. But, if they let the Tibetan diaspora happen, they stand to lose everything - the life they know, their fortune and seemingly bottomless pockets. When the Tibetans disband the Tibeten community and assimilate into the other countries of their choice, there will no longer a category called"Tibetans in exile". They will fight tooth and nail to protect the existence of the community. They will do any to maintain the Tibetan community as Tibetans in exile. but divide them so that ignorant cannot see what is actually happening. CTA is not interested in the community, they are only interested in the government for that is their source of power and money. Dang, such worldly concerns. Pity the Tibetans being led like pigs to the slaughter.
That's just my penny's worth of thought. Either the Dalai Lama is letting them go to hell or they will have a lot reckoning to do to expunge whatever terrible karma they had for them to purify it this way in this life.
