Because Federation is routinely doing the same experiment shit as Space Pirates, but Samus blew up their station with all the dubious experiments, and Adam helped her explicitly against orders
. The Mother Brain was gone and the Federation was still copying it. SR388 is gone. ZDR is gone. X Parasite is gone. The Space Pirates are a non-factor. Phaaze is gone. The war-like Chozo are gone. Samus is the last one in possession of Metroid DNA. The only threat to Federation left is the Federation itself. Where do you think
it's going? Of course
they're going to start hunting Samus herself. Be prepared to find out exactly who was federated in that polity, because it's going to fall apart.
