Basically what @Jaymax said. The Chinese could be pulling wool over our eyes. They probably underestimated the weather for this month and may come back after some time has passed, possibly during the fall.
But we most definitely should not reverse the economic gains we have made. The price should be an equivalent opening up of the Chinese economy for Indian investments in exchange, but definitely no apps. The apps have far reaching consequences and must never be reversed. Rather, more apps should join the list, including making room for future app bans as well.
I really hope those are not reversed.
However, it is equally important that we as a country invest heavily in softwares that are quality products such that they are popular world wide.
That will improve our hold and if done right will reduce the Chinese footprint all over.
