Your cure is worse than the disease. The second such a system existed, it would be gamed to hell and back, and nobody would believe it anyway since they'd all angrily insist that "you shouldn't have counted X" or "you should've counted Y more" and it would just turn into a war over who got to control the system and use it to deplatform their enemies.
It doesn't have to, and indeed shouldn't, be a single system. We'd rather have a handful of independent news checker orgs, maybe some topic-specific ones. Funding remains an exercise for the reader.
