Twitter CEO Jack Dorsey: Big Tech Platforms ‘Definitely Collaborate’ on Censorship ‘Methods’
The first section of the interview, which was conducted by former Gawker staff writer Ashley Feinberg, was made up entirely of Feinberg asking Dorsey why had unfollowed her on Twitter.
“First, I noticed you unfollowed me on Twitter within the past couple of months or so,” declared Feinberg, adding, “Was there a reason why this happened?”
Further in, Dorsey denied intentional censorship of conservatives on Twitter.
“I think it would be easy to believe a perspective if you only look at particular things. And you look at actions based on who you follow and whatnot,” claimed Dorsey after being asked why conservatives believe they’re being censored.
“I mean, people follow people that violate our terms of service and who we take action upon, and if you’re only following those people and you’re not following anyone else, you tend to see that and the perspective is strengthened,” the Twitter CEO declared. “As I said in front of Congress, we do make some mistakes where our algorithms can be super aggressive. But do we build bias into our systems? No, it’s not in our policies, it’s not in our enforcement, and it’s not in our algorithms… So the main thing that we’re focused on is how we stay transparent with our actions and continue to be impartial — not neutral, but impartial.”
