The most ridiculous part of Facebook’s anti-privacy crusade is that FB allows its employees to “lock their account,” making absolutely all information private / only visible to friends, even cover photos.
FB’s website claims the feature is “only available in some countries and on some devices,” but it’s BS, it’s actually an easy opt-in for employees.
It shows that FB understands the need for privacy, but only if you’ll help them spy on others.
You do, but as the above commenter mentioned, you also need to have a Facebook account in order to be a customer of Facebook Ads, and for many other uses.
Purposely keeping that feature exclusive to employees shows that Facebook understands the desire for privacy, but only for those working for them.
