According to joinmastodon.org/about :
Mastodon gGmbH is a non-profit from Germany that develops the Mastodon software.
[…]
Mastodon, Inc. is a non-profit entity in the United States that supports the growth and operational capabilities of Mastodon, including being able to receive tax-deductible U.S. donations and in-kind support.
Doesn’t seem like it was a move, just a different entity. Seems like there’s a bit more history to this if you want to look it up, for example the German GmbH lost its nonprofit status in 2024, strangely.

It was, and still is. It hasn’t moved to the US, it just also opened a nonprofit there, so the US donations they receive from US people are tax deductible in the US. If I remember correctly they have also opened a non-profit in Belgium which is I think where they are intending to actually move their assets and do most of their work going forward as I think they’ve had various issues with the German organization also.
