Conservatives May have Just Won Another Culture War Battle

Conservative may have just won another battle in the culture war as many people are reporting that their QFD shadow bans have been lifted. While it is possible that the lift is not political it was an issue being decried by mostly conservative voices with many people on the left saying it was a conspiracy theory and not really happening. So why did Twitter remove the bans and does it have anything to do with Jack Dorsey testifying before congress in just a few days?
