Because Kha's core playstyle is healthy, and right now it's only his evolved W that is creating unhealthy play. Kha'Zix is intended to be a high-risk assassin who supplements his situational all-in playstyle with utility, and while all but one of his evolved abilities help him achieve that (though Evolved Camouflage is fairly weak at the moment), Evolved Void Spikes is giving Kha safe, reliable poke, which is the complete opposite of what he's meant to be.

Riot wasn't "always unhappy" with the way Kha was being played, though for a long time Kha was just far too powerful in terms of raw damage, and so they nerfed him and gave him tankiness on his evolved R to compensate. That turned out to be a terrible idea, as it made it nearly impossible to kill Kha as he was assassinating people, so that got removed and he got his W buffed. For a long time they had trouble balancing Kha as a utility assassin, but now that they've found his niche and playstyle they know what to do with him.
