Nate Silver turned on paid subscriptions for the Silver Bulletin newsletter by 11 September 2023.

True: the Silver Bulletin on Substack offered paid subscriptions on or before 2023-09-11, shown by an archived subscribe page with paid tiers, a dated post announcing paid subscriptions, or paywalled posts dated on or before that day. Mostly true: paid subscriptions launched within a day or two of the date, with the announcement on 11 September itself. False: evidence shows paid subscriptions became available only after 2023-09-11, e.g. archived pages from that date showing a free-only option.

Set before the research began.

   “All right, took the plunge and turned on paid subscriptions! Most posts will be free so keeping expectations modest, but there will be subscriber-only Q&As and other occasional nerdy stuff.”

   “Silver Bulletin launched paid subscriptions in September 2023.”

E2 is a Silver Bulletin post titled 'Soft launch of paid subscriptions' and dated Sep 11, 2023. The criteria name a dated post announcing paid subscriptions as one way to show the claim is true. E1, a Substack note from the same day, says paid subscriptions had been turned on. E3, the About page, says paid subscriptions launched in September 2023. All three sources are the subject's own records, and no independent source confirms them.
