Don't know if this is the case for you, but 99% of the atrocious or funny right-wing stuff I find there is stuff posted onto my timeline by someone highlighting it. I muted Musk months ago, that weird clickbait Kira account more than a year ago, and that's been enough to clear the direct sources. The "user experience" is much more undermined by the endless bot spam in the replies of every big tweet, likes and follows from bots, and more ads than usual. I've started blocking blue check nonsense on sight, must be up to around 10k by now. Easily the biggest issue in terms of wanting to quit the site.
On youtube, it was the opposite: the algorithm was throwing centre-right and right-wing sources at me every single time - homepage, recommendations, autoplay, etc. To the point that they took over the screen After many rounds of blocks, it's mostly ok (if limited) now.
