Whatsapp has sued the Indian government in the Delhi High Court over the new rules for social media giants which came into effect. The rules require internet companies to “trace” the origins of inflammatory messages sent on the service. WhatsApp said that this law will mean breaking the end-to-end encryption given in the company's service, and "fundamentally undermines people’s right to privacy." The new IT rules came into effect from today and, among other things, mandate that internet companies cannot withhold information on the source of unlawful and inflammatory messaging beyond 72 hours when asked by investigating and cyber security agencies.
