this isn't a 'brown envelopes' situation
There is, sadly, 'pragmatism' at play here.
I suspect the prosecution authorities have looked at the situation, the evidence and the 'public interest gain' and seen just how big Google's guns are.
There was a time when companies were in fear of Governments because they, Governments, could make laws and raise, by way of taxes, almost limitless funds to enforce them. Today, it would be a bold or reckless - or principled (????) - politician who would say to his/her paid officials 'Get this done as a lesson!'. Behind closed doors is so much more effective and civilised when dealing with vandals, isn't it....., my dear?
Google, like some multinational Banks and Media corps and, to some extent, Social media & computer companies doesn't give a toss what Governments in a particular location do or say. They have more perceived and actual power and far better PR machines. Cross them at your expense. They can move.... no taxes, no power to influence...
Are there similarities in Google's privacy plundering with asymmetric warfare between combatants?
