It is important to have harmony if we want to progress. Imagine there is a boat, if we have 2 rowers rowing in 2 different directions, will the boat move at all? It will not. But if the rowers are rowing in the same direction, the boat will move to where the rowers want it to go.
If we still wonder why the Tibetans are still fighting to free Tibet after 60 years, it is because there is no harmony in the Tibetan community! The Tibetans are divided into different groups. For examples, the Dorje Shugden group, the anti-Dorje Shugden group, the Tai Situ Karmapa group, the Sharmapa Karmapa group, the Middle Way Approach group, and the Free Tibet group, etc. With so many differences still exist, it is impossible to have harmony.
As long as there is no harmony, the CTA will not be able to fulfill their promise of free Tibet. But it seems like the CTA wants to keep the status like this, they don't want the free Tibet movement to be successful. The reason is very simple, they want to continue to use their plight to ask for money to fatten their wallets.
