edit: after 20 comments, i’m adding a post description here, since most of the commenters so far appear not to be reading the article:
This is about how surprisingly cheap it is (eg $15,000) to buy a complete production line to be able to manufacture batteries with a layer of nearly-undetectable explosives inside of them, which can be triggered by off-the-shelf devices with only their firmware modified.
They’re batteries. And they are explosive because of the explosives in them. They are discrete things that are explosives.
You’re trying to make a weird, un-useful, pedantic distinction here.
Comment you replied to was making a far more useful correction, because people did not read the article.
It’s a needed distinction because the Israeli committed more war crimes with what they did.
