For ex. one concern over solar inverters is catching on fire. So an adversary can mess with things *waves hands around vaguely* to do so but that's a concern anyway regardless lmao and there are mitigations that can avoid both issues AND you can still buy cheap shit from China.

I don't know what this means. Tampered to do what? It would be cool to know what can actually be done with that access. I doubt the actual alert said anything too different tbh as there is often a lot of rah rah without specifics. These are physical devices so there can be physical solutions.
