Another #FediverseTip (inaccurately called #Mastodon network).
You don't have to stay in the first instance you registered on. In fact, it is advisable to find a different instance where you will feel at home and in agreement with their local community and policies.
While, yes, flagship servers (a.k.a. instances #fediverse software devs are handling themselves) are more likely to stay for the next 20 years or so, those are also often used as "test" servers. Not to mention, their time will be divided between developing their fediverse software and managing their flagship instance.
In other words, it is good that users spread out to different instances.
