Exponential growth in the number of users of social platforms such as Facebook or Twitter will eventually turn into an S-curve because the number of potential users is finite.
Unresolvable The public record could not settle it.
Prediction: Statements about events outside the person's control, checked once they fell due: did they come true?
The second judge would not resolve this claim; the verdict shown is the first judge's.
What would count as true or false
Judged at the evaluation date, using the platforms named (Facebook and Twitter/X). True: reported user counts for both platforms show growth rates that have clearly fallen over time, with growth flattening, plateauing or reversing, i.e. an S-curve and not continued exponential growth. Mostly true: this is clear for one platform and the other's data are unavailable or ambiguous but do not show continued exponential growth. Mixed: one platform shows saturation and the other still shows sustained exponential (constant-percentage) growth. False: both platforms' user counts still grow at a constant or rising percentage rate with no sign of slowing.

“reports roughly 550 million monthly active users at March 31, 2026 and 520 million at December 31, 2025, counted across X and Grok together and deduplicated by sign-in”

“After the first quarter of 2019 Twitter stopped reporting MAU and switched to a narrower daily metric (next section).”

E4 How Many People Use Twitter (X)? Sourced User Statistics GetXAPI (commercial X API vendor blog) · 9 October 2026
“Similarweb measured mobile daily users down 15.2% year on year in June 2025, and Threads passed X in daily mobile users in January 2026.”
Reasoning
Meta's evidence is a single 3% year-on-year growth figure (E1), which does not show a growth rate falling over time. X's data are a combined X and Grok figure that rose over one quarter (E2) and a mobile-only decline estimate (E4), so they are ambiguous. Neither platform clearly shows the S-curve that the criteria require for any verdict tier.
