Because quite frankly there are too may items in the game to counter his ultimate (Hexdrinker, Maw, Zhonya's, Aegis/Locket) and new champions with built-in counters (Soraka's ult, Bard's ult, Kalista's ult, Tahm Kench's devour, etc.).

Plus, counterplay is a big thing that gets more emphasized. There isn't a single champion you could say that Karthus hard-counters. On the flip side, Karthus has many hard counters (like any assassin or great harrasser).
