An IFTAS + Roost partnership seems plausible. They’re also gonna be running a CSAM tool:

..so maybe it wouldn’t be such a bad thing to leave that massive infrastructure cost to a better funded institution (they got that AI-bubble money) so IFTAS can focus on advocacy and essentially operate as an amicable watchdog to keep the likes of Roost honest and informed?
