One possibility is that government steps in in some way or another. For numerous reasons, including both old and recent history in the US, this is problematic. Putting the NSA in the driver's seat rankles.
[Notice Regarding the Transfer of the mstdn.jp / mastodon.cloud Services] We have received several inquiries showing interest in a transfer following the announcement of the end of the mstdn.jp and mastodon.cloud services.
