Yes: Uber is a case study for ethical lapses in tech companies. Nobody could disagree with that.
But holding your developer conference while a killer who used your product is on the loose isn't an "ethical lapse". Facebook has no culpability whatsoever in the murder of Robert Godwin. It's actually creepily instrumentalist of Vanity Fair to exploit that murder to make this point.
And Juicebro is less a story about ethical lapses at tech companies than it is a story about the lack of judgement in tech investors. Juicebro does what it says it will do. It just happens that the thing it says it will do is also something you can do with a Capri Sun bag. Whatever it is they themselves did wrong, it doesn't come close to Uber.
