You mean when it was heavily censored by the woke owners.
Former Twitter bowed to pressure from the US goverment(then democrats) to supress the story about Biden's son's Laptop and maybe other things we don't know about. However the mechanism/hotline/whateveryouwannacallit the democrats used was open both to democrats and republicans it was just the only or primarily the democrats that used it. (it was designed to combat "fake news" but with Biden's son it was obviously used to delay the news to after the elections.)
Which shows that private companies are not the best option to develop mechanisms that combat fake news, i would say it's something you would need on a transparent basis with congressial oversight(or the equivalent systems called/working slightly different in other countries)
Musk sacked all them and let the platform self align
That is indeed Musk's said intention, however his own banning behavior and/or the line twitter now follows is much more pro-republican / right then "self align" a platform like mastodont or other platforms with no clear owner and or management direction are more likely to allow for "self align".
