Hardly surprising since the priority of a true democratic leader is always its citizens. Something that CTA has been getting away with not doing considering the pathetic governing by CTA leading to no significant progress in the Tibetan cause or the welfare of Tibetans to date.
Anyway, taking into account economic and political aspects, it no longer makes sense to openly support CTA, especially considering the possible detrimental economic repercussions from China. In a way, it is always a matter time before such turning point as there is only so much people can stomach the continued leeching from CTA who has nothing to show for after all the generous donations.
As aptly pointed out by Ringo Starr, “Australia, and many other countries, do not suffer fools gladly”.
