If Bitcoin was closed-source and the wallet software had automatic updates which can't be disabled, then you would have to "obey developerss".  But that's clearly not the system we have here.

Devs can propose new rules and then users make a conscious decision as to whether or not they choose to download and install an update containing any new rules.  New rules don't take effect until users and miners are running the code.  As an individual, it may be problematic to enforce your will.  But as a collective, we have the final say.  Not Developers.
