Unfortunately there is no greater reach for the uninitiated. Not. One. Rumble? Lolz. NOSTR? Nope. X? Not even close. When not on YT you're basically on the dark web... And, yes, that is bad.

YT simply has the better platform, reach, experience for viewers, and engagement.

I have seen, however, that many are flying under the radar by not monetizing their channel. There's some interesting stuff that veers towards "dangerous" and "violating TOS" that way.
