Multiple events in 2021 match sacks’s prediction that Congress would hold more high‑profile, theatrical hearings grilling major tech CEOs, similar to the 2020 hearings.

Key confirming example:

• On March 25, 2021, the CEOs of Facebook (Mark Zuckerberg), Google (Sundar Pichai) and Twitter (Jack Dorsey) testified before two House committees in a widely covered hearing titled “Disinformation Nation: Social media’s role in promoting extremism and misinformation.” News coverage explicitly described the session as a marathon, six‑hour hearing where lawmakers “grilled” the CEOs over their platforms’ role in the January 6 Capitol attack and the spread of misinformation, with protesters outside the Capitol using giant cardboard cutouts portraying the CEOs as rioters—a clear sign of its theatrical, highly public nature.

Additional reinforcing example:

• On April 21–22, 2021, a Senate Judiciary antitrust subcommittee held a high‑profile hearing on app‑store competition, where lawmakers “grilled” Apple and Google representatives over alleged anti‑competitive practices and market power in their app stores. This was widely reported as part of ongoing aggressive congressional scrutiny of big tech. (washingtonpost.com)

These 2021 hearings:

• Involved major tech companies’ top leaders (including multiple CEOs in March 2021).
• Were public, heavily covered, and politically charged.
• Featured confrontational questioning and clear elements of political theater similar to the 2020 big‑tech CEO hearings.

Since such hearings did occur in 2021 and fit the described pattern, sacks’s prediction that “there’s going to be more of it next year” was fulfilled.
