I don't get that though, it's not possible to block YouTube ads, so the adblocker, ublock etc, is only blocking ads on other websites unrelated to YouTube. It's got nothing to do with them.
Check out revanced, it's the same thing but with a slightly different name, and it's being actively updated and I just saw the creator post about it on lemmy. It's free, does everything you expect, but warning it's a little bit involved to set it up. But then once it's setup you never need to touch the settings again
Use VPN, switch country to turkey, pay 20 bucks for a year of youtube premium. It sucks, but 20 bucks is more affordable than the 10 per month they are asking.
