> That seems strictly worse, to me. If you have a good tweet with a bad note, you have 1 piece of good info and 1 piece of bad info. If you have 10 tweets with bad info and no notes, you have 10 pieces of bad info.

In the isolated case, sure, but the point is that in the long-run it's more useful to maintain a non-partisan reputation, otherwise it becomes as useless as fact-checkers are. Bad community notes corrodes public trust in them.

> if you want to spread misinformation on Twitter and trivially defeat the lame mitigation that is Community Notes, you just need to make it controversial.

The goal is that the Notes themselves are not controversial. You can have a non-controversial Community Note attached to a controversial tweet.
