Like others below have said, this seems like the absolute wrong conclusions to come to. Someone else mentioned he didn't have enough runway and that's what it feels like to me, too. Someone close to me has terrible migraines and has spent years trying to figure out how to treat them to no avail. If this tool could have shown me data that would have helped the person I love, I would have paid a lot of money for it.
I have no idea what kind of marketing he did and for exactly how long, but it feels like there's a lot of people, organizations, and companies that could have been interested here beyond a few doctors in SF. Like, not to put too fine a point on it, but how many disabled people did he talk to? How many industry groups (American Lung Association, etc.)?
