It's political because it seeks to deflect from political incompetence that caused the wars in the first place.
There was no need to fight the First World War. None. It was a result of political macho posturing in the same way that Trump is posturing over North Korea. It started as a result of Serbian militant nationalism and the subsequent loss of face to Austro-Hungarian pride. And instead of our politicians being real statesman and helping deflate the tension, they stoked it & dragged us into something that was fuck-all to do with us. So because no one would take a step back, millions died.
And if WWI hadn't been fought, there would almost certainly not have been an even more catastrophic second war. And without WWII, there probably wouldn't have been wars in Korea, Vietnam & the Balkans, plus many lower-level conflicts in the Middle East & Africa.
So the poppy, whatever its original purpose, is a deliberate piece of political deflection, taking the focus away from the mistakes of the political class that led to war and onto the sacrifice of those poor sods & their families who had to pay the price of those mistakes, most of whom had no fucking choice but to put their lives on the line.
