It's believable but without proof it's just as plausible as coordinated arson.
You may be interested to know that people whose job requires them to be epistemologically rigorous do not think in this way:

So, uh, keep in mind that some commenters might be Just Asking Questions.
Go back to June 1 for a good example of lots of lightning in the right area. https://imgur.com/a/LcM8sMe
June 6 also has some in the same rough area of Quebec
A plausible motivation could be to keep the people that matters distracted and paralyzed to react while you blow an huge damm and create the second worst environmental disaster since Chernobyl in a well known country, casually in the same f*ing day
But I'm just speculating. All possible options are open at this point except thinking that this is normal. I assume that plagues also helped.

On the evening of June 1, a large lightning storm passed through the area. (You can even see the storm's clouds continuing on towards Maine in your video.) https://imgur.com/a/LcM8sMe
Waves of wildfires starting in the same day can happen by natural causes like a dry storm, but are also a typical signature in wildfires linked to criminal activity. Example: 121 provoked wildfires in the same night and council in North Spain March 2023, a few days after the police stopped a narco operation.
There are some suspicious trends, there is a wave of fires aiming to overpower the firefigthers capability to react. Often at night or weekends. The first spots burnt are often delimited by administrative frontiers, the string of fires follow a road, and fires extinguished reactivate often in the next nights.
The fire starts first on internet. Wildfires are also typically coupled with cyberwarfare mocking environmentalism and scientific facts on social webs and journals.
The criminal thinks that is a hero or adopts a role of victim. There is a lot of self-justifying and blame deflection towards other targetted groups.
At least in Southern Europe this is a reaally common pattern. Your mileage may vary.
