I have been hit a lot by the adblock-block and my default browser for youtube was Chrome with uBlock. There was some back and forth and it still worked around 50% of the time. I took the oportunity to try the youtube experience on a brand new clean browser, not logged in. My seed recommendations were 80% right wing and conspiracy material. I humored the algorithm a bit and after three days I was basically in a right wing/anti science/flat and hollow earth bubble. An interesting experience to say the least. It is basically the opposite of my real world interests. I'd describe myself as libertarian and love to learn about different cultures and I do work in academia.
I have since cut my youtube viewing by about 50-80% and am not using Chrome anymore (except for testing/security). Great success Google and thanks for all the idiotic brainwashing content.
I do get that youtube needs to make money somehow and adds are the way. Unfortunately the experienc is so bad, perormance is suffering etc. that I'd rather have no youtube than youtube with adds.
