As others here have pointed out, you are conflating two very different things. Cambridge analytica deceived people to steal and sell data, and to invisibly manipulate them. These NYU researchers are scientists, whose entire work is only valuable if put into the open, and who are boud do law and supervised by many checks and balances - soft and hard ones. It must be possible to study platforms, and for people to volunteer their data with informed consent to science. Otherwise the entire mechanism of "self-observation" of society falls apart. So yes, it would be good to mention the caveat that Facebook does need to protect users. But no, that's almost entirely not the issue here.
