I'm not aware of a major child porn problem on Facebook. It is a dominant social media platform. You make it sound like it is rampantly abused by a bunch of pedos to share images of naked kids, when in reality the problem is mostly teens sharing photos of themselves with friends or other teens sharing photos in message groups. In one statement you mention not letting their software near their computers, presumably because of privacy issues but in the next you indicate the the only solution would be to enact more spying and privacy intrusion.

Not to defend facebook, but they are hardly the party to blame here, any company to operate anywhere has to bow to the local government wishes,

Companies should not be expected to make a stand against governments.

Indian government has bungled the covid19 response in so many ways already, not helping anyone, not allowing ppl to help each other either.
