Agreed. I think we're all relieved at the harm that wasn't caused by this, but the attacker was almost certainly more motivated by profit than harm. Having a bunch of credentials stolen en masse would be a pain in the butt for the rest of us, but from the attacker's perspective your SSH key is just more work and opsec risk compared to a clean crypto theft.

Putting it another way: if I'm a random small-time burglar who happens to find himself in Walter White's vault, I'm stuffing as much cash as I can fit into my bag and ignoring the barrel of methylamine.
