So, this works for me but ymmv.

I’m on iOS and have the Ghostery browser installed. It’s no longer maintained but I genuinely don’t care for this use.

If I bring up a list of YouTube videos, long press one, and choose to open in a new ghost tab, it treats me as a new unique visitor and -usually- does not show ads. This is without any sort of blocking within the browser beyond what it does by default (and they do maintain an extension for Firefox, so their blocklists stay up to date for the browser even if it’s not actively maintained)

You can repeat this indefinitely with new tabs.

I do also have a pihole set up, but that doesn’t seem to impact YouTube ads so I doubt that’s the reason it works.

I don’t know if other browsers with anonymized browsing would do the same, as I genuinely don’t know of any available on iOS.

Really, if you’ve kept using apple all the way up until now, it’s kinda on you.
