It's literally the most watched television program on the planet lmao.

What about the limits on children under 18 from participating in religious activities?

Preventing child abuse and indoctrination is very cool and good actually. Wish I wasn't exposed to it as a kid.

The demolition of religious sites?

What? Xinjiang has some of the largest mosques in the world lol. And a pretty high ratio of mosques to Muslims (about as high as my own Muslim country's actually).

The requirement for religious leaders to register with the state?

Good. If the capitalist Russian Federation also continued to suppress the church and its leaders like the USSR did and China does, so much of the population would not have become so religious and reactionary.

What's with this obsession with relating Uyghur culture to religion? Sure, so long as it's only adults exposed to religions and it's consensual, fine, but Xinjiang's culture is much more than that, as are those of any region where religions are unfortunately still prevalent.

Religions are generally in decline in every place that's progressing economically, and Xinjiang is no exception. That's a good thing.
