My justification for stating that is that we're seeing people come back to Bluesky whereas people would try to create an account on a Mastodon service, their first post would be confusion and terror, and they'd leave after a few days of trying.
There are daily users of Mastodon (myself being one), it's just that the range of people is much smaller than Bluesky and Twitter due to the comparatively higher barrier of entry.
