Not 1984 but just standard 20th century type dangerous cult of personality with one person having way too much power.
But if it's not Musk, it's the DNC, if it's not the DNC, it's someone else. I don't see how it detracts from X still being a good platform. You have to curate your TL, yes -- but you've always had to do that!
Some of these problems pre-dated Musk's acquisition of Twitter, and some of them will no doubt eventually plague BlueSky as well. But that is kind of the way of social media, nothing lasts forever and people tend to hop from one sinking ship to another.
As for not understanding why people hate Musk. I am loathe to get into politics on this site, but he is (himself) actively using X as a platform to meddle and stoke tensions in a number of democracies throughout the world. That is part of why a lot of people dislike him, and it also casts further doubt on X's future viability as a global content distribution channel, if countries start blocking it.
What do you think was happening on Twitter before Musk turned it into X?
The media moved from hating Trump to Musk because the latter appears to hold more political power over the former, he already got his ways on H1B visas and a few other issues.
Musk also appears quite pathetic/sociopathic to non-MAGAs. He has many children he barely sees and often insults online, he was caught lying about a video game recently, and that's not even bringing up the sexual assault allegations.
He also switched from supporting Obama and considering himself a socialist to becoming the largest donor of the GOP in a few years.
Also, please reread Big Brother, because that comparison is very misplaced.
