The current algorithm is far from being perfect (it's an MVP) and will never be, but with more measurable inputs and after multiple iterations with the help of the community, it can lead to an analogue of "S&P500" for OSS, that's worth using for donating to reduce the risk of the global OSS supply chain we all rely on.
As with publicly traded companies, having a decentralized set of private donors with skin in the game helps a lot to efficiently evolve the approach and make it harder to exploit in the future. And on the contrary, I would not trust an algorithm created and maintained by some state-owned or simply very large institution.
