Oooh, yeah-haya!

I'm not arguing that. They should. I know if I had music being used by trump to support his campaign I'd have some personal opposition to it. Lars is a special kind of asshole that I lost all respect for years ago so maybe I'm overly critical of him.

All that said, the military using a song in a training video is such a stupid thing to get worked up over. It's basically bitching about a fair use case, because it's not any kind of external promotion of the military. Just an internal video. Which is really an on brand example for Lars' special kind of cuntiness.

Metallica were just a bunch of tone deaf (speech)

you don't have to clarify that. You really have to be a ham fisted fucking idiot to do the things compositionally that metallica does with the music they have to hand. Master of puppets should have made a recurring theme of the chromatic (ish) intro, and they throw it away, they bash away at the same shitty, caveman riff for eight fucking minutes. And Justice for all has a great intro, and it gradually degrades until basically nothing is left.

check out this song that uses a theme similar to master of puppets for a better way to use a similar musical idea https://youtu.be/FoGoEQ8DUDo?list=RDFoGoEQ8DUDo&t=18

Not even in the slightest. Metallica went far above and beyond everyone else hunting down little old ladies to sue.

99% of bands didn't make money from album sales, which is what makes all the hand wrangling over Spotify funny. Musicians idolise a world that never really existed.
