Musk himself had to make deals with bad people (Saudi royals, Russian oligarchs) to afford it.
Yes, you do have media networks that are clearly partisan: Fox on one side, MSNBC on the other (though not nearly as blatantly), but Twitter is/was an open network for _individual users_ to communicate and broadcast their views. Elon has turned it into a partisan media network.
I find it rich that the right complained about social media election interference and censoring and now turn around and crow for what Musk is doing and cancel their own if they say anything Trump doesn't like...
Certainly the Twitter board and CEOs had political biases. But they didn't have the control over the network and were ultimately accountable to public shareholders, and even to the Twitter userbase themselves (pissing off a great deal of them is bad business). Elon is accountable to no one, and he has enough $$$ that he can piss off anyone he likes.
X is now Fox 2.0.
As for the politics, I don't disagree so much with Republicans as I do with Trump. He supported an attempt to violently overturn a democratic election, something that only happens in, to use Trump's words, "shithole" countries. That for me ends the discussion right there -- no need to debate the merits of either candidate.
It just shows how far off the path of democracy the USA has fallen, and Musk along with it. He's just another wanna-be dictator now.
