Yes and no. While it's true that occasionally there will be natural disasters such as lightning strikes that occur in high-risk areas during times of high winds, power lines are carrying huge amounts of power all the time and thus coincide with high winds more than lightning strikes. As an example of how to mitigate this risk, PG&E has a policy of cutting power to lines temporarily during high-risk times like extreme winds in high risk areas — although in another sign of negligence in this case, they failed to follow that procedure during the windstorm that led to the outbreak of the Camp Fire.
You can't prevent all disasters, but you can mitigate risk, which at least reduces the incidence rate of disasters. It's starting to look like PG&E was negligent in their prevention efforts. I agree that doesn't mean they're entirely to blame, but as a society we still need to hold companies accountable for negligence so that we help incentivize safety.
