like i have stated before,the real enemy of bitcoin is the government.the government hates what they can't control so i think the more bitcoin continues rising they will want to know more about its origins and how to control it.
i'm also among the group of individuals who believe that satoshi is not an individual but a group or even an organization so its never going to be possible to know who he is cause its not a person.even if one of the founders of bitcoin is found it doesn't still change anything.the government will probably interrogate and threaten the individual to try to get information and i still feel it won't work because those who invented bitcoin thought of all the loopholes and closed it so i'm sure that no matter whatever enemy bitcoin might have they won't prevail.
Unless Satoshi, whether it's an individual or a group, decides to come out in public and reveal their identity, no one, even governments around the world, can find their real identity because they left no marks or signals that could lead anyone to them and that is one of the reasons why Bitcoin is so popular because people know there is no one controlling it which isn't the case with fiat currencies or traditional financial institutions because they are completely under the control of central authorities.
They don't like it, obviously, because as you said, they know it promotes decentralization and they don't want that. If a government loses control over the financial holdings of its citizen it basically loses control over them because you can only make someone obey you if you have some sort of control over them. If people start using Bitcoin to store their money or save money, traditional financial systems will be finished.
