Here is the deal though, if you don't like their product don't use it. If you feel their dealings are unfair and biased don't use their product. I don't like CNN or Fox News' product, thus do not watch either channel. I also do not like Oprah's channel, hence I don't watch it.
You wanting the government to force a private company to "show their work" is kind of scary. Would you also like the government to tell Willie(or a former presidential candidate) to divulge posts that were deleted and users that were censored or banned?
This fairness that you seek will never be there no matter who is running Twitter. It seems as if Musk is right leaning, do you think that if a politician he supports asks for something to be censored or promoted he won't do it? I'd guess he would. It is the same as if Cael would call Willie(and he answers) and says hey this poo poo head is saying I'm involved with some illegal activity on your board please take it off. I'm guessing he takes it down, but just a hunch.
Unfortunately our political parties have driven a stake between Americans and made use pawns in their game. They thrive on divisiveness. They have made it so that we are forced to pick a side when 95% of us are in the middle. When they do that people who have power in media(social and print) have the ability to promote or suppress things they do not like.
Asking for fair, unbiased, proportional enforcement will not happen, what you think should be removed may not be what I think should be removed. Unfortunately for right leaning people they are the heavy minority in the tech world and thus they think the nerds are picking on them. Maybe it's revenge for the high school bullying.
