Agreed, it can work for those wanting to be an admin (and know enough to be “dangerous”). I think the bigger issue comes when you want to open services to the internet, because unless you are an admin you probably don’t want to do that without a proxy (and possibly firewall) of some kind in front of your home network. Which is kinda what I was thinking with this anti-Cloudflare post. If you are interacting with the Internet you have to trust a network and hardware outside of your own. And I think it’s naive to fear the 3-letter orgs being inside Cloudflare, and then thinking that putting your data in a datacenter you don’t control is any “safer”.
I think ultimately if the 3 letter groups want your data that bad because you’re on some list, I think the internet as a whole is something you should probably be avoiding anyways. And for randoms, if they are sweeping up data like that you can be sure they would do it at more than just Cloudflare.
