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.
will update my reply for this post later.
While I agree that because bitcoin is decentralized no single party has complete control over the system, however I believe the miners and many of the large crypto whales can have a huge amount of impact on the price and therefore often hashing power.
