I think nobody can control or own the bitcoin system like they can not control and possess the technology by email and the internet. I think Bitcoin is no different than a mobile application or program that offers a personal Bitcoin wallet and allows users to send and receive Bitcoin.
Bitcoin is controlled by the people all over the world.
the system of sending and receiving is also held by the people (miners)
they are the one who gets involved in it.
This is why governments and bank are getting on their nerves as they want bitcoin to be regulated but its very hard.
