Transparency International: Google more corrupt than Apple

The article talks about anti-corruption measures and visibility of reporting. It does not give a measure or even an indication of corrupt or inappropriate behaviour on the parts of the companies.
It's really good though to see how organisations like Transparency International are one day going to change the world by slow, gradual, naming and shaming that encourages companies to change their behaviour. Corporations can't have ethics due to their shareholder responsibilities so it's good that we will be able to implement a positive feedback loop to get them to improve.
