The part at which he says it is difficult to break up those companies is interesting indeed.
I think a few further topics we could investigate are e.g.
Antitrust:
- Are there any (bi-partisan) efforts to strengthen anti-trust laws that enjoy wide support? There are certainly people like Elizabeth Warren supporting it like outlined in this old article or in her 2020 campaign but how broad is the support? → Here is a first good article about the state of Antitrust in April 2022 and another one in Dec 2022.
- Are we able to identify leading scholars/professors/lawyers who share their assessment of how difficult it is for agencies like the FTC or DOJ to win major anti-trust lawsuits against companies like Meta?
- Which courts are deciding those cases and which are the main laws they use for their decisions?
- I heard that Meta loosing its FTC Instagram + WhatsApp case more than 10 years after the acquisition and needs to divest is seen as quite unlikely. How much could a new administration change this outcome and increase the risk? As an example could a newly passed law change an old anti-trust case?
Free Speech:
- How wide is (bi-partisan) support to change Section 230? (Bill would need to pass the house and senate)
- Which are the major laws and agencies which regulate free speech and the censorship of (misleading) informations today? (Partially answered here)
- How much resistance would republicans face from democrats if they want to implement plans like outlined here? What are ways in which democrats could hinder the trump administration from achieving its goals?
Criminal investigations:
- Are there any arguments to be made why certain decisions of Meta like to block Trumps account would be unlawful or have all action from Meta been in clear compliance with laws and regulatory practices so that we can be confident that there is no risk coming from that side?
Other
- Are there any other major concerns that Meta is facing when it comes to political risk from a new administration?
Given the breath of the topics I think it might be good to organize the informations in a Wiki article.
