Ads and members only

I need to share something that's annoying me on YT. I'm a paying YT premium user, I'm annoyed that almost any YouTuber is paddling his own ads on the channel, why is YT allowing that behaviour?

And one other thing "Members only" is another phenomena, not enough that I pay for premium, that I have to watch the ads of the YouTuber i need to pay extra to see his content.
