Zuckerberg says Facebook "altered its DNA" in 2018

Facebook CEO Mark Zuckerberg, who started 2018 out with a pledge to "fix" Facebook's myriad problems with data privacy, misinformation, content moderation and user trust, posted a year-in-review message Friday declaring he is "proud of the progress we've made."

Big picture: "Addressing these issues is more than a one-year challenge," Zuckerberg now admits, but "we've now established multi-year plans to overhaul our systems and we're well into executing those roadmaps." In the meantime, as shown by a year that started with the Cambridge Analytica affair and ended with embarrassing revelations about security bugs and opposition research, Facebook continues to be a high-output generator of controversy and scandal.
