Thanks, Dr. Caraway.
I will say that freedom of expression is foundational. If you pass a law that just incentivizes a focus on harms, you incentivize companies to put in rudimentary solutions that, in fact, backfire. There's been a lot of evidence of backfiring, where what ends up being silenced is racialized and other marginalized voices.
For the requirement on companies, if we care about harms, we care about harms to rights, so it needs to be a dual focus that social media companies have. They need to focus on how they protect and promote freedom of expression and show that to a regulator. They need to demonstrate the steps they are taking that are contextual and bespoke to their services.
