Some of the youtube channels I watch also have channels on Peertube instances or on Odysee. Both options allow me to follow using RSS. I prefer my views to go to these platforms, so hopefully more content creators see these as viable hosts for their videos.
Peertube is also federated, so you can follow channels from your Mastodon account (and I think Lemmy too). You could also spin up your own instance if you like too.
