What this tells me is that I am not the kind of user you are targeting. I don't either need or want any such trade-off. I'm knowledgeable enough to make my own decisions about security; I don't need a third party to do it for me. So if your distro will end up insisting that I cede any control over what software runs on my machine to a third party, it's a nonstarter as far as I am concerned.

That may or may not change your overall strategy, and I emphasize that it's your decision either way and I would not have a problem if your response is simply: "Well, we are targeting a particular kind of user and that's just the way it is." (I would simply go find another distro to run.) But I think you need to be clear about what kind of users you are targeting and what kinds of control you expect those users to give up to third parties, so users know what they are getting into.

I also think that this idea of having third parties control the security of your computer is against the basic Unix/Linux philosophy, because the whole point of running Linux or some other variety of Unix is to opt out of the walled gardens and third-party controls that other operating systems that I won't name force users to accept. So if you're going that route, IMO you're going to have a tough time explaining to users why they shouldn't just go ahead and run one of those other operating systems instead.
