Sharing because I found this very interesting.
The Four Thieves Vinegar Collective has a DIY design for a home lab you can set up to reproduce expensive medication for dirt cheap, producing medication like that used to cure Hepatitis C, along with software they developed that can be used to create chemical compounds out of common household materials.
The Open Source Initiative has a giant list of licenses that anyone can use to make their works fully open-source.
Some are just for code, but I’m sure they could be adapted to things like medicine, if needed.
