As people in tech, they should really know that the purpose of a system is what it does. Not what it’s intended to do.
They are lending their brand, their platform and their technology to the researchers, indiscriminately. Wether they like it or not, Visible will be associated with the researchers, and they researchers will be associated with Visible.
Hiding behind ethical approvals is not good enough, and if it’s not feasible to vet the studies, they at least have to acknowledge that they will be directly contributing to patients being harmed because the patients would not have come into contact with the researchers without the intervention by Visible, and that they consider the benefits (primarily faster recruitment to good studies) to be greater than the costs.
Although with the ethical and moral duty to first, do no harm when you’re in the field of healthcare (which they most definitely are), it could reasonably be argued that the costs are not acceptable.
