Obviously this is nothing new, and the cigarette industry has been profitting off addiction for decades, but I never expected the same thing (except the very immediate threat of lung cancer) to happen to tools that could have been optimized for so much good instead.
And the worst part is that some of it is just so incompetent. I've been trying to break away from Facebook for a while, and recently (the past year or so) I started realizing that my Facebook feed always shows me the exact same posts in the exact same order for days, to the point where I know exactly what post will be first when I open the website. Where is all the Facebook money going? What are these people working on? What are they doing?
