Google could earn fees if they setup their own mining nodes. I doubt enough GPUs exist to make it practical, but they certainly could divert some of their collective CPU power to make the support of bitcoin more 'tangible' for them.

I'm still on the fence if they would actually go for the idea, as some have already mentioned, they have many different projects going on.

We're aware of a few things:
1) Facebook dominates the world and has created its own currency, mainly for use in wildly popular FB games from companies like Zynga.
2) Google is launching Google+, which is a direct competitor to Facebook. Google has its work cut out for it.
3) Google is engaged in the Google Wallet project, for fund transfer mechanisms... but Google is NOT creating its own currency.

Given these facts, if I were a decision maker at Google, I would at least consider the strategic decision to implement Bitcoin in Google+ and across the Google Wallet platforms. This would directly undermine FB credits, and if FB credits fails that is a HUGE win for Google. Consider that Google should already be observing how its relatively unrestricted Android community has amazingly caught up to Apple's iOS "walled garden" environment... the lesson applying perfectly to Bitcoin vs. FB credits.

If Google helps legitimize Bitcoin, FB credits will fail, and Google+ will be further strengthened against Facebook.

Is my Machiavellianesque thinking sound?

All large corporations fear the unknown. CEOs forget their roots and the fearless way they pursued their dreams. It's time for Google and FB to go the way of Myspace, AOL, Compuserve, etc. The future CEO of the company that promotes Bitcoin, Ripple, and other decentralized currencies will find a place in history and sit next to his or her predecessors.

Multi-brand corporations, f*ck the customer to get rich together and above all: rule the world and make all human 'useless eaters' our slaves!

Cool down man.

It was a ',' (comma), and not a ':' (colon) written after 'multibrand corporations'. Those corporations are only part of the listing, not the subject, and were mentioned because they obfuscate the fact that the 'choice' they offer are not really a choice because they have the same mother/owner.

That 'f*ck the customer' was aimed at different corporations that collude against their mutually shared customers, and the 'above all: etc...' was aimed at the banks.

Happy now? 

Haven't you heard of externalities? Corporations can hurt you even if you are not a customer or employee.

Right now the entertainment industry is dictating terms to the computer/electronic industry: even though the latter is a much larger industry. It means that since 2006, it is much harder to find a general-purpose computer. If you think your computer is general-purpose, take a second look at any paper work or EULAs that came with it.

The free market relies on the price system. Unless everybody switched to bitcoin, there is a lot of government intervention there. Even if the world adopts bitcoin, government intervention is going to be needed for contract enforcement.
