Suggestion: Reach out to your local government, emergency service provider, and/or news org. Let them know that Twitter has ended public access to content and that Mastodon is a working alternative *today*. I did this on the weekend with my local emergency folks and this morning I got a reply back saying they had noticed the embedded Twitter feed on their webpage was broken.
They didn't realize Twitter had cut that service. Now, hopefully, they are considering their options including Mastodon.
