TL;DR: The current Mastodon-signup is only removing the confusion of users on first glance, because it either hides the server-choice altogether, or leaves them with a choice that is impossible to make at this point of their Mastodon-journey. Instead, it should introduce them to decentrality on a lower scale, with a handful of handpicked servers to choose from, such that the decision makes sense to them and shows them the merits and fun of the concept instead of scaring them away. Ideal would be to give them a sense of agency. Then, chances are higher that they consider migrating again in the future and eventually internalize it as a permanent option of the digital world.
You could even have other more accurate analogies: for example, you can use the telephone analogy. You can be on Verizon and still call people that are on AT&T, joining different providers. Heck, mastodon is a more realistic digital townsquare. You can join and be in any town, but that does not stop you from going into other towns to hear what they are talking about over there
