Nobody owns the Bitcoin network much like no one owns the technology
behind email. Bitcoin is controlled by all Bitcoin users around the
world. While developers are improving the software, they can't force a
change in the Bitcoin protocol because all users are free to choose what
software and version they use.
In order to stay compatible with each other, all users need to use software complying with the same rules. Bitcoin can only work correctly with a complete consensus among all users. Therefore, all users and developers have a strong incentive to protect this consensus.
