Companies rarely do basic research, and that's why it's very important to keep up public funding for it.
There is a company creating a 3d-printed chemical reactor. By downloading a schematic and buying some raw substances, you can create your own lab. It can be used to synthesise drugs in remote areas, such as on Mars, or to make generics for cheap. The exciting part is that the reactor schematic can be downloaded and shared easily. It can also make illegal drugs just as easily as 3d-printers can print guns.

Also, for drugs that do make it to market, efficacy and side effect information is published as a condition of drug approval, at least for new drugs.
Whether basic science research papers should be behind a paywall is a wholly separate issue, but the life science community largely shares its finished products. Indeed, there’s even a push to share early stage data, too.
