Might there be potentially significant differences in what options are available to respect (or even completely understand) accountability, between amateur and citizen science?
I commend your emphasis on accountability as opposed to arguing priority or for credit for a discovery or technological advancement. Examples from the history of science may be illuminating.
Prior to USA official involvement on the side of the Allies in WWII, a group of students and young scientists approached a physics professor at UC Berkeley,
J. Robert Oppenheimer, to evaluate emerging technology including radio and radar, with potential wartime significance and to notify government officials. This was a separate endeavor from
Leo Szilard's "Einstein letter" warning President Roosevelt about the dangers posed by nuclear fission experiments.
At that time much electronic and aerodynamic science and engineering involved amateur societies around the world who would trade data, information and equipment designs. These amateur groups often included a prestigious professional in the field, not just for the attached respect, but for improved access to information and to help keep their efforts on track. Oppenheimer advised both amateur physics societies and graduate students including members who would later join him in the
Manhattan Engineering Project.
Fast forward to the aftermath of WWII where Oppenheimer steadfastly accepted responsibility for the development and deployment of Allied nuclear weapons. Oppenheimer went on record, much to the detriment of his professional career, opposing development and proliferation of thermonuclear weapons. Oppenheimer used his office as head of the Atomic Energy Commission to direct efforts toward peaceful use of atomic energy.
Oppenheimer represents the quintessential 'citizen-scientist'; leading and advising amateur and professional scientists, mathematicians and engineers; always accountable in public for the results of his actions.
