Why Facebook is Evil

Some people are accusing Facebook of a "massive" data breach, in which a foreign company took a bunch of data about tens of millions of Americans and used it to influence them to vote for Donald Trump.

Others are saying that Facebook did nothing wrong, that they didn't do anything that wasn't listed in the terms of service. From the Atlantic, here's a brief summary of what happened:

In June 2014, [an England-based Russian] researcher named Aleksandr Kogan developed a personality-quiz app for Facebook. It was heavily influenced by a similar personality-quiz app made by the Psychometrics Centre, a Cambridge University laboratory where Kogan worked. About 270,000 people installed Kogan’s app on their Facebook account. But as with any Facebook developer at the time, Kogan could access data about those users or their friends. And when Kogan’s app asked for that data, it saved that information into a private database instead of immediately deleting it. Kogan provided that private database, containing information about 50 million Facebook users, to the voter-profiling company Cambridge Analytica. Cambridge Analytica used it to make 30 million “psychographic” profiles about voters.

The key thing here is that while only 270,000 people explicitly gave their consent for their personal data, this Russian professor got hold of 50 million people's data because Facebook let "friends" look at personal data.

That data included all kinds of personal information that can be used not only to influence you, but to commit identity theft. This data not only included Facebook posts, personal photos, and Facebook likes, but also birthdates, addresses, phone numbers, educational histories, lists of family and friends, names of pets, what people ate, where people went, what what people did and when they did it, and tons of other sensitive information on whatever people happened to blab about themselves on Facebook.

The reason this enables identity theft is that much of this information is used by various web sites to validate your identity: birthdate, addresses, mother's maiden name, names of your schools, names of your pets, etc.

Facebook thinks it's doing nothing wrong. They claim that apps need to have access to information on your friends so companies can write apps to perform critically important services that we simply could not survive without, like wishing you happy birthday.

If Facebook friends were actually real, close friends and family, this wouldn't be as big a problem -- but it would still pose a serious breach of personal data. Do you really trust your elderly grandmother to understand that taking a pop quiz on Facebook -- and getting paid a dollar! -- can give information on her family and friends to hackers and Russian spies?

What makes it worse is that many people somehow think that the number of Facebook friends is an indicator of social importance. So they accept friend requests from people they barely know. A lot them were phony accounts created by Russians trying to influence American politics.

But the real root of Facebook's evil is that the public image of what it does has nothing to do with its true purpose.

People mistakenly think that they are Facebook's customers and that Facebook's communications service is the product. This is utterly false.

Businesses, advertisers, opinion researchers and political operatives like Cambridge Analytica are Facebook's real customers. The real product is you and your data.

Facebook sells your secrets to anyone who will pay for them, be it advertisers, identity thieves, political operatives, foreign governments, or private investigators working for people looking for dirt on cheating spouses.

The best thing you can do to protect yourself is to destroy your Facebook account, delete all the data and never log in to Facebook again, hoping that your data hasn't already fallen into the wrong hands and that Facebook will actually honor their commitment to delete it.

The second-best thing you can do is unfriend everyone except your family and your closest real friends. Of course, since those people already know all that stuff about you, there's really no reason for Facebook to have that information in the first place.

The third-best thing you can is enter false information in your profile: never use your real birthday, or address or other personal data for social media accounts. The whole idea that companies need your birthday to make sure children don't see "adult" material is preposterous, since kids can just lie anyway.

Deleting your Facebook account will have immediate benefits. You will get back an hour of your time every day.  You will feel less depressed. You will be less angry.

Ditto for Twitter. If Donald Trump deleted his Twitter account, the world's net happiness quotient would increase by 7 billion!
