Healthcare privacy laws are not a hindrance in the US. Basically all one needs is a business agreement with a HIPAA-compliant entity and one can send PHI data.

Healthcare privacy laws are not a hindrance in the US. Basically all one needs is a business agreement with a HIPAA-compliant entity and one can send PHI data. And certainly so if the patient opts in. So I would say it is 100% due to the siloing and proprietary enshittification endemic to the industry. They don't want to help science, they want vendor lock-in.
