When you post on Twitter(1) or Bluesky(2) you grant them a broad perpetual license to use, modify, and sublicense your content. You effectively make them co-owners of your content. They can mine it and monetize it. They can even sell it. When you post on Mastodon(3) most instances take no license at all. That's right, they tell you what they are doing with your content—storing posts and delivering them—but no license.
