The WhatsApp policy has now been put on hold till May 15. It aims to share commercial user data with parent Facebook. The Indian government has also written a letter to WhatsApp CEO Will Cathcart to withdraw the policy.
In a quarterly earnings call with analysts on Wednesday, Zuckerberg said that the company has moved the date of this update back to give everyone time to understand what the update means.
"All of these messages are end-to-end encrypted, which means we can't see or hear what you say and we never will, unless the person that you message chooses to share it and business messages will only be hosted on our infrastructure if the business chooses to do so," Zuckerberg said.
More than 175 million people message WhatsApp Business accounts every day.
"We are building new features to make it even easier to transact with businesses in the app," the Facebook CEO added.
The matter is also under discussion at the Delhi High Court.
On interoperability between Messenger and WhatsApp, he said that the biggest difference between the two apps is obviously the connection to Facebook and the kind of same identity and graph that you use on Facebook comes with you to Messenger.
"So even if you can send messages across the different apps and there is more interoperability and we bring the same world-class privacy features to both, I think that, that will still make the apps feel fairly distinct," Zuckerberg explained.
