I don’t know what to tell you; the same site has Hetfield making a statement that’s pretty to the contrary:
https://blabbermouth.net/news/james-hetfield-is-honored-metallica-music-was-used-by-us-military-to-help-us-stay-safe
So really he couldn’t give a shit.
In the article you linked, it sounds like Metallica’s PR people did the asking; the interview with Ulrich is pretty equivocal:
So not going to advocate or condone the use of their music in torture.
It is possible that James and his bandmates have different opinions about it. Hetfield has always come across as a bit dumb/rednecky(?) fwiw.
However the band as a whole did ask the US army to stop using their music.
