I thought it was very obvious. Just check your local firefigting department or police. From local Governments to the President, they use twitter to inform their citizens sometimes exclusively. Meaning there is no other place to go for this information.

Unrelated but - Doesn't it bother anyone that it has become a necessity to use Twitter and they demand your phone number to login simply to view the Tweet?

I'd like to see reasons why Twitter is not a public square.

I believe federal, state and local institutions have reporting requirements that ensure the information is also publicized on their website or available in paper form upon request. I don’t think it’s legal to put important government info exclusively on Twitter.

Twitter is 1 method of quickly dispensing information, but that information then gets more widely distributed through traditional news networks. For example, I use Twitter almost every day but I never once read Trump’s tweets. I heard about them by watching TV or reading a news article.

When anyone from police to the President need their message heard, they put it on TV.

Also, a town square is for the public to communicate to the public. People seem to use FB, Reddit, Instagram, etc. all for that purpose. I’ll grant that it’s one of many virtual town squares, but it’s not a monopoly, so I think “the de facto town square” is a bit of a stretch.
