uninstalled the app last night. everything on my timeline was about Elon. got a push notification from him even though I didn't follow him and explicitly said I don't care to see his tweets and that was it for me.
You can mute specific words, hashtags, usernames, and emojis from your Home timeline, replies, and notifications. Learn how.

Did you try muting?
I have never used it but it seems like a pretty good feature for people who want to use Twitter and not get bombarded with the trending slapfights.
If you mute a word, hashtag, or account name it is supposed to block it from your timeline and notifications.
If you did try this and it did not work that would be good to know.
