I do find the reactionary response a bit disturbing. Having been caught up in the trap of "fact checkers" for reposting a political cartoon and similar, I'd definitely prefer the community notes approach. All said the inability of many to have a rational conversation with those they don't completely agree is very wrong on so many levels.
Criminals are not willing to have rational conversations. But they just won a free pass from the platforms.
Bot activity is best handled through system pattern matching, not correcting political cartoons.
You also assume that the people doing the fact checking are better informed or otherwise better people than those with the access to propose and vote on community notes. This is unsubstantiated at best.
