Because of laws passed after the Enron scandal, publicly traded companies are required to retain internal communications for long periods of time. So if you're going to blame anyone for this, blame the government. Also the owners of Twitter knew that Musk would have access to these messages. That was priced into the deal. Executives and managers at publicly traded companies are very aware of information retention policies and make sure to avoid putting certain things in writing. That's why so many of the emails are along the lines of, "Can you take a look at this?", or "More to review from the Biden team.", instead of being explicit commands. It's just a miraculous coincidence that every single one of those requests results in censorship or banning.

> there is no clear evidence that they explicitly favored one party, and to be honest- I don't really care if they do

Ah yes the old, "It didn't happen. And if it did, it wasn't that bad. And if it was, they deserved it."

If you truly believe that there's no clear evidence, then I don't know what to tell you. Taibbi shows emails where Twitter and the US government collude to censor true information that people wanted to read. That is a big deal.
