Imo... people should be able to download stuff for free if they’re able to see it for free. The “you can see it but you must watch an ad” model is weird and leads to unenforceable/wacky situations like this (I’m not really a stakeholder tho so who cares what I think)
... funds OTA television. Also funds YT.
With OTA, it is okay to record OTA broadcasts using a VCR, so I'm not sure why youtube-dl would be different.
