Good answers. I would say research grants and bounties are both subject to regularity capture. Bounties are high stakes and thus more worth being corrupted, but also fewer and hopefully more in the public eye and so exposed to more scrutiny.

But, as I led with, I'd be fine with just purely public research leading to generic drugs. Drug bounties are just the "post-capitalist" fallback plan if the old school state-bureaucratic approach isn't work.
