It's not talked about more because it's a crazy conspiracy theory that has no merit. After all these years of scrutiny the worst vulnerability required physical access and disassembly in order to preform a hardware attack.
The people who believe this conspiracy theory, like many others, peddle misinformation to prove their point. No matter how much you try and debunk it you can't change their mind.
Yeah, see that's the other side of the story that doesn't seem to be told much either, and I'm interested in that too. It does seem like some researcher or journalist should have blown the case open by now if this thing were systematically providing telemetry from everyone's "powered off" (but still plugged in) machines to an intelligence agency. Can you point to an article or paper that thoroughly debunks the claims as crazy conspiracy theories?
The claims shift around so that they're nondisprovable. Someone could say that ME is a backdoor that has never been activated and will be undetectable until some future day when it is activated.
