The ISIS/YouTube cases pending as of October 2022 were Gonzalez v. Google LLC (about YouTube recommendations and ISIS) and the related Twitter, Inc. v. Taamneh Anti‑Terrorism Act case.

On May 18, 2023, the Supreme Court:

1. Twitter v. Taamneh (9–0 for Twitter and other platforms)
   The Court unanimously rejected the plaintiffs’ claims that Twitter, Google, and Facebook had "aided and abetted" ISIS under the Anti‑Terrorism Act and held that the allegations failed to state a claim. (supreme.justia.com) This was a win for the platforms, not a narrowing of their liability.

2. Gonzalez v. Google (no ruling cutting back Section 230)
   In Gonzalez, the Court explicitly declined to address whether Section 230 protects YouTube’s recommendation algorithms, vacated the Ninth Circuit’s judgment, and remanded for reconsideration in light of Taamneh—"punting" on Section 230 and leaving its broad protections in place for the time being.

Media and legal analyses at the time uniformly characterized these outcomes as avoiding limits on Section 230 and effectively preserving broad immunity for big tech, not as rulings "against" Section 230 protections. (cnbc.com)

Chamath’s prediction was that the Court would go 9–0 against maintaining broad Section 230 protections for big tech in this context (i.e., a unanimous ruling finding no Section 230 protections here). In reality, the Court (a) ruled unanimously for the platforms on non‑230 grounds in Taamneh and (b) declined to weaken or even opine on Section 230 in Gonzalez. The net effect was to preserve broad Section 230 protections, not to reject them.

Therefore, the prediction is wrong.
