It's a good question. Does nosrt support videos at the same level as YT? I don't think so. Once it does then the content creators can post the content on nosrt, without a YT link, while continuing to post on YT so we/they can reach a much larger audience then nostr can provide. I think nosrt has about 1 million daily active users compared to YT that might have 15 to 20 million. Fact check that for sure.
