The phrase &quot;medical data should be free&quot; is a trojan horse. Your medical data is yours and should always be your own -- unless you yourself say otherwise for specified used of specific parts of your data. Otherwise, due to market forces and financial constraints, your data will be turned against you before anything else.<p>The quality of medical care for the majority of people doesn&#x27;t depend on the freedom of your data but on the quality of communication between doctors and patients and between health professions. These are low tech problems though for which you cannot get much research funding.
