Lift the Synth ban? This was explicitly stated near the end. It was seemingly 1-2 days during the events of the last episode and the ban was lifted. Really? That the Romulans took over the Synths is a fact. The Synths killed 90,000 plus damaged the whole planet Mars. They're clearly susceptible to being misused or misled (Romulan use, and the "evil" one which killed another Synth which Soong then deactivated.) They have a super-powerful-ally which can be brought up at any time to destroy organic life. If the Synth ban were from the Federation Council, which seems reasonable, why would you reverse it in this timeframe without first making sure your Synths were not going to be hacked again, and having at least some debate? Its one thing to let Soji and friends live in peace, another to relax the ban. We didn't even see a Picard speech on this because frankly its absurd.
