The prediction was explicitly conditional: if Republicans retained control of the U.S. Senate and/or the presidency after the 2020 election, they would then turn Jack Dorsey into the main symbol of tech censorship in the subsequent term.

In reality, Joe Biden and Kamala Harris won the 2020 presidential election, defeating the incumbent Republican ticket of Donald Trump and Mike Pence. Democrats also ultimately secured effective control of the Senate for the 117th Congress (2021–2023) after the Georgia runoffs and the January 20, 2021 swearing‑in of Ossoff, Warnock, and Vice President Harris, giving Democrats the majority via the vice president’s tie‑breaking vote. Republicans therefore did not retain the presidency or a lasting Senate majority for the post‑2020 term described in the prediction. (en.wikipedia.org)

Republicans had already been aggressively attacking Dorsey and Twitter over alleged censorship in late 2020, including high‑profile Senate Commerce and Judiciary hearings where GOP senators focused on Twitter’s handling of the New York Post and broader claims of anti‑conservative bias. These hearings clearly cast Dorsey as a central face of alleged censorship, but they occurred during the pre‑election and lame‑duck period of the existing GOP Senate majority, not in a new term contingent on Republicans retaining the Senate or presidency.

Moreover, Dorsey resigned as Twitter CEO on November 29, 2021, and was replaced by Parag Agrawal, further limiting the relevance of the specific scenario envisioned (ongoing Republican control plus Dorsey as Twitter CEO throughout the subsequent term). (en.wikipedia.org)

Because the key condition of the forecast (Republicans holding the Senate and/or presidency for the next term) did not occur, we cannot observe whether the predicted behavior would have followed in that counterfactual world. For evaluation purposes, that makes the forecast ambiguous rather than clearly right or wrong.
