I don't think it is justifiable. Google's policies are a bandage for gaps in their algorithms, rather than fix their algorithms (admittedly, this is hard and it's not like they aren't trying) they have reached a point where they can use their monopoly power to dictate how websites act. They punish behaviour which hurts their main business - adwords. I would expect an anti-trust case in the coming few years.
