There is some wiggle room for contractually clarifying who is the 
controller and who is the processor, but it is not unlimited. I my day 
job I have had one case in which there was a clear overlap between 
controllers and data subjects, but it is pretty rare. You could also 
argue that there is shared controllership in such cases.

Either way, it would require the data subject to be in full control of 
the data, which is rarely the case.
