As I said, we don't need to know anything internal about Twitter to know for a fact that they bent over backwards to elevate extremist right wing voices. Because they elevated the most important extremist voice for 4 years as he violated the terms of use for their platform. In effect, we all had one TOS, and there was a different, more permissive TOS for the leader of the US MAGA-right wing movement, the most extreme version of right wing politics in America. That's blatant, confirmed, irrefutable, systematic bias and special treatment for conservatives on Twitter, pre Musk.

In case you want to discount the Twitter report as a false flag, here's a report from NYU that independently confirmed Twitter is biased toward conservatives. It also found the same for Facebook: https://bhr.stern.nyu.edu/bias-report-release-page
