Facebook was looking at which links I clicked on, and it was noticing that I was clicking more on my liberal friends' links than on my conservative friends' links. And without consulting me about it, it had edited them out. They disappeared.

Whether it's Facebook or Google or the other companies, that basic principle that users should be able to see and control information about them that they themselves have revealed to the companies is not baked into how the companies work.
