Google.com has already abandoned objectivity
Haven't they already agreed to push piracy sites lower in the list? Sites they deem to be using dishonest SEO tactics get pushed down or delisted too (not a bad thing, but it's still tweaking results). Or recently they hid 8chan (home of Gamergate) based on abuse reports with dubious motivations.
It's been a long time since google simply applied a magic algorithm and kept their hands off, if indeed that was ever true. I don't quite understand why this "right to be forgotten" thing is such a big deal to them.
Biting the hand that feeds IT
