I do over 8 million views a month and I don't believe that Fullscreen is providing ANY ads on behalf of my channel.
CPM may not based on the network. It may be based on what the advertisers will pay to reach your audience who watch your videos. There are other factors as well but I am not in a position to talk with specific knowledge.
Now if a network does provide ads for your channel, then you might see higher CPM's. The problem is that you can't verify that they are actually doing so.
Even if you get higher CPM's, it is very unlikely that they will make up for the percentage of revenue that you surrender to the network.
You're not stupid, you're ignorant. You just don't know and to be honest, most of this information is not readily available. Advertisers, networks, and YouTube keep the secrets under wrap. I know quite a bit but I wouldn't say that I am all that knowledgeable either.
As for some people being so gung-ho for networks, many of them are recruiters or receive some type of benefit. Many of them do not have very popular channels. I am being polite and not trying to be condescending in any way. Some people like being part of a 'sorority'. Some people like the music that some networks have a license for you to use with your videos. Some people just don't care and like the 'badge of honor' of being under a network.
For me. I have no problem relinquishing some of my earnings in exchange for some kind of goods or services that a network would provide. I am coming up to the end of my year with Fullscreen. It was my first network experience. I will not be resigning. It has been a terrible experience filled with lies and deception. That being said, it doesn't taint my opinion on networks. It helps educate me to the fact that you really need to know what a network can provide and what they can't. What they say they can do and what they can't.
Judging by your content and what I know about networks, you're not a good fit. Maker has a 'family' vertical but I would wait until all of the changes take place with movie studios buying networks. In my opinion, Disney just paid $500 million for Maker Studios. Disney will need to make that money back. I doubt that they will be giving very favorable contracts to creators for awhile.
