It is not enough because the true goal of moderation is not to hide content people don't like, but to lock out people the majority of people don't like so they can't communicate or work together to spread their (probably hateful) message.
Putting it on a blockchain is abdicating responsibility for any and all content, saying "hey, we just wrote the code, we don't store or propagate any of this ourselves."
Putting it on a blockchain doesn't magically remove responsibility. Twitter would still likely end up hosting that blockchain, since nobody else is going to foot that cost, and then they would still have fully responsibility over it.
If they just want to decentralize & use peer-to-peer instead they could also do that, and a blockchain still wouldn't be a useful aspect there. That's just a mailing list.

I'm still kind of amazed that the government hasn't cracked down on bitcoin miners for hosting child pornography yet; every full node is hosting it. If the government ever wants to crack down on blockchains they have a valid legal excuse. The longer they go without cracking down, the more it seems like we as a society are accepting the existence of a censorship free medium of communication.
I'm not convinced that nobody else would host it. If they really made a blockchain anybody could post to it would seem difficult to stop other companies from making frontends for it.

How are those companies going to make money from hosting tweets? Are you letting blockchain hosts inject things? If so that's a security & privacy nightmare just waiting to happen. If not, it's financially insane to host it unless twitter pays people to do so. And if they do that then hey they're simply contractors for twitter, and twitter is again bearing the full burden of responsibility.
The same question can be asked of Twitter. Twitter serves up other content alongside tweets, and makes a profit doing it (as of last year). Is this a privacy nightmare? Yup. Is it more of a privacy nightmare if a different company does it? Depends on the company. Maybe a given user will trust a given provider more than they trust Twitter, or maybe they'll like their ad policy more, or maybe they'll be willing to pay a premium to not be served ads, or maybe they'll want to search through tweets using more specific filters than Twitter allows. To me, choice of provider sounds like something that should increase security for those who desire it and educate themselves. For those who don't, there are other tradeoffs they can make.
This all assumes I'm interpretting Dorsey's statements correctly, and of course I may not be.

Why do you assume that? Modern blockchains are not proof-of-work, and the only info you need on a blockchain are permissions and encryption keys to data on other distributed storage networks (e.g, IPFS.)
So the cost isn't really very high, and probably worth the tradeoff for groups that feel alienated or disenfranchised.
Modern blockchains don't host images and face twitter's level of traffic, either.
Bandwidth & storage isn't free. Why would anyone voluntarily just do that for Twitter? Even if it's literally entirely free to setup & host, that's still someone's time & motivation to do so. People do this for blockchain because they're trying to get rich off of it. There's no money in hosting tweets.
