Like balladbird mentioned, youtube is not remotely a profitable service, so the answer is no. As well as the fact that, as Chessrook44 said, social media are monopolistic by nature. Why would you go on the smaller platform either as an creator or a viewer?
Now in the long run all kinds of things might change. New technology could make uploading and storing video's so cheap that an alternative could be viable or that an entity like youtube could lose relevance. Anti-monopoly regulation could forcibly break up youtube (not sure how that could technically be accomplished). Youtube won't be around forever, but for the foreseeable future they will remain unchallenged.
