A greater possibility is that the entire bitcoin concept/operation has been created and supported for some generally unknown further purpose.
Actually that is way more far-fetched than believing Hotmail and Gmail were built with the intention of spying on our communications, as those are closed platforms, in open technology there's always someone watching and verifying every line of the code...
And thinking that some shady organization will have a plan like "Hey, lets build a great technology with the power to substitute the entire economic system and unleash it into the wild and lose complete control over it and maybe it will gain enough popularity and maybe some day, some how we will be capable of harnessing its power to do something", that's tin foil hat mentality big time.
There are way more popular and widely used open source software and I don't see the nutjobs making outrageous claims about them, like linux, apache, android, open office, and so on, well we see then making claims, but not as much as with bitcoin technology.
