With some caveats. For example, I'm sure all the patients whose data I work with would rather not have it spilled out over GitHub.

Can you reasonably anonymize it?

For some things, yes. For others - not really. And there have been groups, historically, that have not been served well by "Everyone has access to this data". Given the need for their consent and cooperation, I generally side with what my subjects want their data to go toward, rather than some nebulous ideal.
