I'll give my usual contribution to RSS feed discourse, which is that, news flash! RSS feeds support video!
It drives me crazy when podcasters are like, "thanks for listening to our audio podcasts. We also have a video feed for our YouTube subscribers." Just let me have the video in PocketCasts please!
I feel you but i dont think podcasters point to youtube for video feeds because of a supposed limitation of RSS. They do it because of the storage and bandwidth costs of hosting video.
I'd think they'd get it back by not having to share their ad rev with Google. There's something to be said for the economies of scale Google benefits from but with cloud services that's not as relevant as it was.
