Autistici/Inventati shuts down after 25 years, citing the US Treasury terrorism designation

Sources: primary, collective site, Treasury release, discussion
Summary: The Autistici/Inventati collective announced it is ending 25 years of running mail, blogs, and websites for its users, citing the US Treasury designation. The announcement sits on keepitfree.ai rather than the collective's historic domain, and inventati.org, which the collective controls, carries the same shutdown notice. The collective states autistici.org was made unreachable without previous notice and that the remaining domains may follow, and the Treasury release designates the collective under Executive Order 13224 for materially assisting an act of terrorism.
Why it matters: Users with mailboxes, blogs, and websites on the platform have to migrate before the remaining domains go unreachable the way autistici.org already did.
Follow-up: Track whether the remaining A/I domains go offline and whether the designation is contested.
