The hearing yesterday was always going to just be a political show due to the current election but remember back to Zuck in 2018 regarding Cambridge Analytica or earlier this year with Zuck, Bezos and Cook. These congressmen are just clueless about tech entirely and apparently aren't seeking expert help in advance of these hearings.
As a big tech employee myself, I absolutely believe that a lot of these big tech companies should be broken up and I can clearly see things that we are doing that aren't good for the consumer. Congress just isn't asking the right questions and isn't asking for the right information.
