France’s data protection authority CNIL gave a sharp warning to
WhatsApp by issuing a formal notice, criticizing it for
“insufficiently” cooperating. The decision comes a year after
European Union privacy authorities said they had “serious
concerns” about the sharing of WhatsApp user data for purposes
when people signed up to the service. […]
The merging of WhatsApp’s data with Facebook was a first step by
Facebook last year toward monetizing the platform since the social
network’s Chief Executive Officer Mark Zuckerberg bought the
company for about $22 billion in 2014. The EU’s 28 privacy chiefs
were critical from the start and as part of their probes across
the bloc, in a letter to WhatsApp co-founder Jan Koum in October
that stressed their concerns.
The data transfers from WhatsApp to Facebook happen in part
without the users’ consent, nor the legitimate interest of
WhatsApp, CNIL said.
