In DSC, Section 31 was not a secret. Pike knew about it. Spock knew about it. Even the low-level Discovery bridge crew whose total amount of character development consisted of them having names, knew about it.
Fast-forward 100 years. Sisko has never heard of it. Bashir has never heard of it. Dax (and how old is Dax again?) never heard of it. Etc, etc. Yet there are even former Starfleet officers who are still alive and even had direct contact with Section 31 (i.e. Spock) who would have known of its existence. So why is everyone in the 24th century acting like they know zero about this organization (even its name) when it was common knowledge only a century before? (Other than my usual stock answer of ‘because DSC isn’t in the same continuity as previous Trek,’ which isn’t the intent of the people producing DSC)
