Facebook (NASDAQ: FB) has faced a lot of backlash this year from both users and advertisers over its lapses in data protection. And that backlash is wholly justified, following the revelation of management's mishandling of data shared with and used by Cambridge Analytica to target political advertisements on Facebook without users' authorization.Some big advertisers halted their ad campaigns on the platform earlier this year, but that doesn't seem to have slowed down Facebook's growth.
