jwildeboer, (edited ) FTR, the US501(c)(3) for #Mastodon was already planned for quite some time, the non-profit status in Germany being revoked doesn't seem to be directly related to that.
"Set up a US non-profit branch (501(c)(3)) with a board of governors to become eligible for larger grants from US-based donors and allow US donors to make their contributions tax-deductible."
