It's obviously sad and very disturbing, and should be the kind of thing that wakes people up. Unfortunately, the US media is very careful on downplaying/misreporting self-immolations, even though in theory it's the type of macabre story that they'd capitalize on.
I think it’s treated similar to suicides where giving them certain kinds of publicity causes a predictable uptick in suicide rates. How it took them so long to start applying the same standards to mass shooters, I’ll never know.
