In all fairness, the old WhatsApp did not have end to end encryption. And the partnership with Open Whisper Systems for implementing that has been announced after the acquisition announcement. It was probably planned in advanced, but it was developed and deployed during Facebook's ownership. And I know that the old WhatsApp was promising privacy and a no ads business model, but you can't really promise privacy while unencrypted chat messages are flowing through your servers. That said, Facebook can still violate people's privacy just by having access to the metadata and I hope such lawsuit will revert this decision, at least in the EU.
