I'm not going into this too much since it's not the topic, but I have to add this.
A few years ago I would have said the exact same thing (note that I never said anything about NSA or whatever). Then I found out the hard way that it's really important to either disable the thing completely (which is too hard and some parts are effectively necessary for booting the cpu and can't be 'fixed') or at the very least get it updated to the latest version - which hopefully contains security fixes.
In short: my router/firewall was (and actually still is) a regular PC connected directly to the internet. No connections to be witnessed that way ...
Fun fact: I once heard about reprogramming the ME as a low-cost IPMI for consumer hardware, never looked into it though.
Very applicable here: I was an adventurer like you once, then I took an arrow to the knee ...I feel like the notion that the ME is a backdoor is a conspiracy theory. Many people (including me) screen their internet connection with whatever they have like a firewall or something, and have not noticed weird connections. I think it id a terrible design, which combined with RMS and his tinfoil-hat-brigade, has spooked people. That said, I think it is a security vulnerability, but not a secret NSA plot

This^ It is NOT necessary for running any PC. And each and every one of my servers has an IPMI (and most of them actually do not have an IME because of that).You won't. It has full access to the TCP/IP stack and can send packets independently of the OS - bypassing any firewall.
Before you denounce its critics as "tinfoil hat", consider well what place this kind of tech has on a personal computer.
It also has full access to memory.
