You think this case makes the FBI look good? It took a month long media circus, made Apple look like the good guys, pissing off most of the tech community—all to unlock a single phone that likely has no useful data on it. If they had wanted to advertise their ability to unlock iPhones, they would have just done it, and done a press conference about how they unlocked it and got lots of good information. Instead, they look like they were desperately scrambling, before some "Canadian girlfriend" showed up at the last minute and saved them from looked even more foolish.

Sure, from Apple's side, it would have been better had it gone to court and been established that the government isn't allowed to do what it was trying to do, but... I don't see the FBI trying the same tactic again, and, here's the kicker—if they can't establish the authority to force Apple to unlock phones on non-secure enclave machines, then when they need a secure enclave equipped phone unlocked, it's going to be a lot harder to use the All Writs Act to force Apple's hand.
