There's almost always at least a software developer (or technical person of some sort) calling out "Hey, are you sure we should rank by $X? It will have this edge case in situations $Y and $X?". Usually they get steamrolled by a "product" person who's invented some new terminology for whatever shady shit they are pushing now. "It's just growth hacking" "complimentary contextually relevant ads will improve the user experience".
People know. They always know. They just choose to feign ignorance when they get busted.
There's been hand-wringing about Youtube funnelling users to extremist content, and it always comes to down to "the algorithm" as if there's nothing that can be done about it.
Someone had to choose to implement the algorithm. Someone had to choose the metrics it was optimized to meet. Someone had to go, "Children are being drawn to extremist videos after watching PewDiePie and that's okay."
You enter into the comment section and it's automatically sorted by Controversial. At least that's how I see it.
