Bitcoin developers have no control over anything whatsoever, least of which the network and people's transactions or keys! In fact bitcoin was created so that we no longer need any third parties and centralized authorities to control our money, in other words to get rid of the system you just explained here.
Bitcoin is free from these central chain of authority and all the developers and miners are working voluntarily and don't have the control over network which means they can't make any changes to the network and the whole process carried out in a decentralised manner from one end to other not involving third party and we don't need any changes in the system.
