That's the legacy of communist Chinese, on the surface it seems they are encouraging religious practice, but fundamentally their policy is still "religion is poison". That's why Tibetans in Tibet nowadays do not learn much Buddhist philisophy, but only are good in prayers, because prayers do not really require you to think and analyse, and the communists prefer the Tibetans not to think and analyse.
That's why, when you visit monasteries in Tibet nowadays, you will feel empty, there is little teachings, classes. Only some chanting by monks. The real Dharma is not the building, it is the teaching, which is thriving now in the monasteries in India.
