When apple puts an advert for an apple show in front of for all mankind, that's an advert.

Maybe I put up with it and it just adds to my subconscious seething, or maybe I get the episode elsewhere because if I watch on jellyfin I don't have the advert. Of course that then harms the show as my viewing isn't counted, but they've cancelled it anyway so perhaps it doesn't really matter.

If it isn't an advert, then at very least there's a button to disable it.
