Only one person I followed commonly left Twitter, many posted mastodon accounts, but they haven't reduced how much they post on Twitter so it's unclear if those accounts are in use at all, just mirror tweets, or aren't used at all. Most who posted mastodon accounts did it in the "just in case" vein (as they apparently thought it likely that Twitter would just stop working) rather than actually wanting to use it.
