Yeah. When you're in caca you need the lazy brilliant maverick to pull you back to the floating line. Hardworking isn't a necessary CEO trait. It's something for the lower rungs, ex. COO, CFO, CTO etc. Being hardworking might very well mean that the person is merely competent but compensates with raw effort. A slipping company like Yahoo doesn't need somebody like that; they need a heavy hitter.

Her tenure at Google was more or less luck. She was lucky enough to get in early and be at the right place at the right time.
She's been an absolute trainwreck at Yahoo. Her efforts at improving the brand have been scattershot at best, desperately flailing to find some gimmick that would raise Yahoo's profile. Perhaps the only worthy acquisition has been Snapchat, but that won't save them because she's made no effort to promote it or integrate it with Yahoo's other holdings, to say nothing of the fact that the core ad business continues to be an absolute mess.
