I think the "The Worst Diagnostics In The World" section is a bit simplistic about what traceroute does tell you. It can tell you lots of thing beyond "you can reach all the way". Specifically, it can tell you at least some of the networks and locations your packet went through and it can tell you how far it definitely got. These are extremely powerful tools as they rule out lots of problems. It's useful to be able to hand an ISP a "look, I can reach X location in your network and then the traceroute died" and they can't wonder "are you sure your firewall isn't blocking it?"
It's still a super-common tool for communicating issues between networking teams at various ASes. That the author's ISP thought they were too small to provide reasonable support to is not a strike against traceroute. Rather, it's a strike against that ISP.
