I've gone so far as to only go to YT with a browser that clears everything on close. I don't log in to YT, all I do is keep a local file that I use as my home page where I keep the link to the video tab of content creators I enjoy.
When you go in "fresh", the world is your oyster for approximately three videos, maybe four, then the algorithm has completely made it useless. So, I either go through a link to a creator and see what they've been up to lately or I go to a fresh YT homepage and search for what I'm looking for. The first search is probably still heavily curated, but it seems to give me more interesting options. When I find a video I like, I go to the creators page and add the link to my home page.
I don't log in mainly for privacy reasons, but it also causes me to only be able to search my particular bubble, pretty much. Going in from the outside gives me much better results, at least before I've watched too many videos in a chain. I'm a patron on patreon for a few my favorite creators, which I generally swap around every now and then for those who have Patreon accounts. I don't think I've ever bought anything from a creator's sponsor. It weirds me out that randos on the internet are now expected to be commercial shills and personal brand curators as well as video creators.
