Why Indian versions of whatsapp, facebook, Google, Apple wont work ?

China has banned American products for so long And they have chinese version of these products for them.

Its now paying them off !

American companies have zero data of who & what and where of chinese people.

A recent attempt of twitter version called "koo" failed citing expensive costs to keep it running.

But is that the actual reason ?

I want to understand logically why Indian version of these products wont be a good business in India ?
