Zuckerberg’s Data Stance Facing Privacy Backlash in Europe: Tech

As delegates gather for the Mobile World Congress in Barcelona next week, they’ll see the smiling mug of keynote speaker -- and Facebook Inc. boss -- Mark Zuckerberg splashed across brochures and websites. Chema Alonso better represents the prevailing mood.

The scruffy computer whiz oversees digital security for phone carrier Telefonica SA.
