Almost everything in your comment is highly likely to be wrong, simply because of one fundamental difference between WaPo/WSJ and Twitter: Twitter contributors are not employees.

Stating unilaterally that Bezos & Murdoch exert no influence over the content of their publications can't be grounded in any fact because any potential influence they might exert would never be public knowledge. It's falsifiable (as many commenters have done with Murdoch) but it's not provable. There's a lot of circumstantial evidence Bezos does too: it will probably remain circumstantial since he is in a position to keep it that way.

Twitter content being crowdsourced means that Musk as owner has far less direct influence. All he can really do is censor, which is exactly what we've seen play out.
