Yea, it is just such a shame.
I think it took me a day or so for it to sink in. I mean, I wasn't a "super fan" by any means, but I still followed them through their latest album (I also kinda found the post-AONO sound not always "for me" - if that makes any sense)
I've also been going back through their discography...
In case you don't have it - here's my favorite live recording I have of them, from the "Their Law: Greatest Hits" tour stop at Pukkelpop

It has (probably) the best performances of "Firestarter" and "Warning" that I've heard
