As a non-American having American politics, or the American viewpoint of world issues, shoved in my face every day gets exhausting.
Some will see this as a big improvement for their Twitter experience.
Seeing an inflow of abuse caused by the elimination of any semblance of moderation, coupled with not wanting to see racist and fascist propaganda pushed by god knows what bad actors, is not exactly adequately described as "disagree with Musk on politics".
You're making it sound like people stopped using Twitter because they had an irrational dislike for someone, when even long-standing advertisers decided to drop Musk's Twitter due to the cesspool of hate speech and propaganda that it became.
Maybe you see political discourse by default? I dunno, just saying it's not all flamewars.
