the main reason is because we can look it up on twitter or facebook, why should a youtube channel with very long video be better to get the information. there is this channel call "The Know" that stalls and misleads everyone on news, it's so bad that one developer DMCA them.
This is the main reason news channel is dying, too many youtubers are losing to social media post, the channels are lying to everyone and we have better things to do.
