It absolutely is an ad. I think it is a US Army work around.
The US Army wants to get into long range fires. It needs precision targeting capabilities. Those need aerial assets. That means the US Air Force because the USAF is unlikely to let the US Army get into 707/737 type ISR assets.
So this becomes an off the board capability that the Army can buy - just the way the Ukrainians are buying commercial imagery.
The Canadian overlap is to do with dollars and manpower. If the government doesn't want to be seen spending more than 2% of GDP, or increasing the CAF's manpower budget then civilian contracting is a way out for them. If all you are doing is observing and reporting, especially remotely, then you don't need to be on the CAF regular strength. Those positions can be reserved for people putting themselves in harms way.
