You haven’t noticed major differences in search results? I used to see reputable sources like Reuters and AP in the top few tweets when you search for a news story. Now it’s people like that catturd guy.
I don't think most people use search except at major news events so most people wouldn't notice. Twitter search has always been broken and a common thing to complain about. At least now under Musk it's not 60% gay porn spam accounts anymore. No clue how the precious people messed it up under those few weeks. Even worse than the spam comments YouTube had.
