> it is not technically decentralized, it is Twitter (a centralized platform)
Community notes are generated by users and not the platform it's not perfect but better than having a mainstream media oligopoly deciding what is truth and what isn't.
> If it were truly fully decentralized, it would be vulnerable to such attacks even more, right?
The algorithm tries to prevent this kind of abuse. "the Community Notes rating algorithm explicitly attempts to prioritize notes that receive positive ratings from people across a diverse range of perspectives". See Vitalik analysis: https://vitalik.eth.limo/general/2023/08/16/communitynotes.h.... But from what you're telling it looks CCP found a way to game it.
Good point that the algorithm tries to compensate for the perspectives, but I’m sure it still comes down to a popularity contest.
Generally, the platform determines the algorithm of which note wins, so that’s centralized. The algorithm depends on what kind and how many users vote and how. Those users exist on the platform which requires registration and can deny any given user. Centralized.
Further, no guarantee that the actual algorithm in production matches the one made public, but I guess they have no reason to lie here.

It’s not just me telling, the tweet has been up so far and community note does its best to awkwardly convey the controversy that would’ve been otherwise completely lost due to the ill designed way community notes work.

It isn't clear if polarization score have only one dimension where it would be great to capture US culture wars but fail to capture nuances outside of that or if it's more complex than that.

Yes, not perfect but still better than the traditional media oligopoly.

The algorithm and the data are open. It is reproducible.

I checked the tweet (https://twitter.com/MOSSADil/status/1745921315498811752) and at least now the community notes show a different content:
> Original video, which provides a better look at the plate (鄂F1573警),indicates that the video was shot in Hubei, China.

Many here are biased against Elon and Twitter for political reasons so they are too quick to pass judgement.

This means there was yet another update since I looked. The previous note at least made the user suspect that there was an attempt to point fingers at some other country. Now it merely corrects the location in China. It is good to link to a higher quality video, but I don’t rule out that the note will with time drift to suit the agenda of the government.

He killed the feature that labeled accounts associated with governments though.
I think community notes are not his invention so I don’t blame him for them, but they are very poorly implemented and are strictly worse than tweets themselves.
If they applied the same algo to weighing tweets and replies, they could’ve gotten the same results but without making people trust blindly. But of course this defeats the point of paying for Elon’s blue checkmarks.
