I don't think this is a problem that's specific to any one bias, nor will it go away when "rogue employees" are dealt with. I think this is an issue that's inherent to turning dials to tune what you want people to see in any kind of content-aware way. I also don't think that's necessarily problematic, but it probably is for Facebook because it has a near monopoly on its particular type of service, and because it gives the appearance of being content-neutral.
