Self promotion is a form of advertising, doubly so if it’s done for the purpose of attracting revenue via some means. People can opt into it if they want via subscribing/following but it’s still advertising.
So yes most “authentic” content is just people advertising themselves. I would prefer not to see that unless I have opted into it.
