Real answer, Elon made it more friendly to the far right (the racists and Nazis) and unbanned a bunch of them who had previously been banned for being too racist and Nazi. Then he introduced a subscription service where you pay to have Twitter spread your content.

So that started a doom loop: The far right bought the additional views, people who didn’t appreciate the extra racism and Nazi views on their timeline left Twitter, but the view boost was paid for so it kept pushing those views to the fewer people who remained, then THAT volume of hate pushed more people away, etc.

It probably got to the point that they couldn’t keep paid views high enough with just people who care about politics and they had to just push at all costs, eventually to you.
