The FBI lost control of the "going dark" narrative. Part of it unraveled thanks to outside vendors. Two vendors -- Cellebrite and Grayshift -- announced they could crack any iPhone made. This shot holes in the FBI's theory that locked phones stayed locked forever and thereafter were only useful for hammering legislators over the head with until they cranked out an anti-encryption law.

The second unraveling was the FBI's own unforced error. Supposedly it couldn't count phones without software and the software it had couldn't count phones. What the FBI and others claimed was 8,000 uncrackable threats to the safety of the American public was actually a little over 1,000 phones. As for the latent threat posed by these locked devices, that's still pure speculation until the FBI starts handing over some info on what criminal acts these phones are tied to.
