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. Community Notes does not seem to be able to address that issue in its current form as it seems to require notes not be very controversial and, as discussed in the article, many things these days are quite controversial. Or, in other terms, 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.
