That's a poor comparison to this case.

Would Mercedes be liable if the car (i.e. the algorithm) decided to run over someone?

Does the algorithm "decide" to show something, or is it operating mechanically, driven by the inputs of the user?

[leereeves]

If it is operating mechanically, then it is following a process chosen by the developers who wrote the code. They work for the company, so the consequences are still the company's responsibility.

[int3]

The car is following a process chosen by Mercedes' engineers (to go forward when the user presses the accelerator.) The newsfeed is likewise following a mechanistic process driven by user input (they wouldn't be showing misinformation if users weren't uploading and sharing them.)
