I am assuming they are also responsible for the clinical trials, but I'm not sure about that. It would make sense, though, because navigating the approval processes of the different agencies requires very specialized experience and domain knowledge.
Bottom line is they want the company to be successful, so their long-term plan is to profit from making drugs. If they lived in a socialist economy where no such profit was possible, they would not have bothered, and then there would be no cure. If that is the world you prefer to live in, you have options (North Korea, Cuba and Venezuela currently, the rest having collapsed or transitioned to free market some time ago).
Given the timelines and uncertainty, I don't think 1B and 1.3B are materially different. Both require 2 doses per vaccination.
