First, why are you sure that this didn't influenced elections results?
100 people killed or still missing. Many killed only in one wildfire by the mud floods that came later. Helicopter pilots and firefighters killed. More than 13500 homes and human structures destroyed only in 2020 and 2021.
Not all fires were deliberated, but too much wildfires were deliberated to be statistically random. We'll never know how much of them were attacks. A few people managed to spread chaos in entire villages, forced the authorities to evacuate tens of thousands of people, nuked the local budgets, and introduced a lot of tension in the economy and society. And it cost them practically nothing.
And I'm not talking about the people killed and injured, or the natural resources lost (like millions of liters of freshwater stored in the area that were lost and have some, non negligible, economical value).
"Maynard's fires were placed in the perfect position to increase the risk of firefighters being trapped between fires" [1]
If this is not terrorism, nothing is. Don't fool yourself. The only difference between a "non cleaned" and a "cleaned" forest (whatever it means), is that the terrorist will carry its own can of gas.
