Playing games with power grids etc is arguably much higher stakes than fighters messing with each other, or even with passenger planes. Or navy ships passing too closely.
Edit: I guess that it was more like a heads up for adversaries. As in "don't think that we won't". Just in case you didn't think we were that hardcore.

It's the classic: "What are you going to do, hit me?" response after hitting someone. Just be glad most countries maintain some semblance of civility.
From whom do they reserve that right?
Basically, the US has warned adversaries.
The original statement I could find [0]:
>recommending, in response to the "most extreme case" (described as a "catastrophic full spectrum cyber attack"), that "Nuclear weapons would remain the ultimate response and anchor the deterrence ladder."
I think this is referring to an unprecedented attack which intentionally kills many citizens. It's hard to imagine a scenario where nuclear weapons would be the warranted response, even if the cyber attack killed people, but I don't think the statement should be taken literally.
Either way, this is not that. These are the same espionage and sabotage games every big nation plays. Russia has been and probably is in many of our energy SCADA systems. China, too. And we're in theirs. That's just how things go in the 21st century. It will undoubtedly escalate; the real question is who will pull the trigger. (The US did at least once against the IRA, though that was in direct retaliation to disinformation campaigns aimed at destabilizing the US.)
Edit: As in "WarGames".
That didn't actually happen.
Russia has been attacking critical infrastructure in the US for years. This is at best an incredibly latent response from a government who in many cases welcomes these attacks.
