Probably because it still earns them money over not showing you anything!
I have come to believe that over a period of time producers and consumers both will realise that the middleman cares more about it’s own cut over either of them.
Less cynical thoughts;
1. I don’t know if and what kind of controls/flexibility YouTube allows on demand side, but it could be a “foot meet gun” story. ie advertiser is new to platform and messed up targeting and/or is over-bidding.
2. Advertiser might think 1 cent CPM is worth it, no one else bothers to bid on your data (based on your description) - still kinda ties into cynical view.
