I'm sure Metallica doesn't really care, but it's ironic given that a large part of the mess we're in today (with the large platforms fearing copyrighted works showing up for 1/10th of a second) stems directly from Metallica.
I did however see a video by Tom Scott recently about how the copyright system is broken; and it's not the platforms fault.
Right... so the reality is, they probably feel like the myriad Napster users they sued, a little guy getting trod on by the big gorilla in the room... which is delicious in its irony.
I mean... they will probably care for about five minutes then head back to their no doubt richly textured, varied, and stimulating lives. Not the most satisfying gotcha situation
