You could make an arguement of gmail centralizing control in email, but I don't think thats what you are doing. Mastodon is part of a federated network. Most people who use Mastodon belong to a large server rather than hosting your own, but you can be part of that network without being part of mastodon.xyz. You can join mastodon.social, or any number of those mastodon servers, or host your own. The same is currently true for email.
