He failed to answer a simple question of who can their users migrate over to when they are not happy. Wonder if that will come back to hurt him.
Sure, but that doesn't mean we don't evaluate new issues as they crop up. If FB is unwittingly aiding in a genocide then it's reasonable to ask questions. People killed other people before nuclear bombs were invented, but they changed the playing field and allowed for far more destruction than was previously possible.
Sure Facebook could implement some system that uses AI and humans to catch hate speech. Then the debate shifts to what exactly is hate speech, should Facebook a private company be determing what hate speech is? Truth be told it is the Senators who should be determining what hate speech is and providing the laws that balance freedom of expression and hate speech. It isn't Facebook's job. Yes it should be discussed. I felt Senator didn't think through or didn't know what the implications of allowing Facebook to determine what content is allowed and what content isn't allowed.
