It takes some effort, but you can get the recommendation algo to clean up your feed. My youtube account of 15 years was flooded with political content. Mainly just opinion stuff and lot of AI slop. So I just unsubbed all channels and started clicking the don't recommend this channel or I don't like this content. It took couple of months, but my recommended videos are back to what I liked watching. Mainly dev and hobby stuff. For channels that I do like that are non-political, I just keep bookmarked links that go directly to their channel page.
