If Bitcoin created with the intentions of controlling or exploiting then why it has to be decentralised and not can be controlled by anyone even the creator itself?

We may have different theories when we look from different perspectives but I can strongly say Bitcoin is something that's created after someone is just fed-up with the centralized money that's just printed out of thin air and made the people to believe it has actual value.

However the elites has the power to Bitcoin for buying even now it may increase their influence but never gives them any control over the network that's the fact.
