Totally support this and am rooting for alternative ad networks - especially ones like this. However I think it's fair to acknowledge that without tracking it's inevitable that you'll have less value to provide to advertisers. We can't have our cake and eat it too.
We definitely get a lot more than that for US developers (pricing here: https://www.ethicalads.io/advertisers/#pricing). The CPM is averaged across all the traffic in the network, as most sites have traffic from eg. Poland, as well as the US, and the average ends up quite a bit lower.
We also want to underpromise and overdeliver, so we generally keep our published numbers on the conservative side.
