This thread is silly.
I live, race, and ride in SF - the home of Strava. I know people who work at Strava. I ride and race with them as well.
I've never, ever, been in a group ride where someone does something dangerous in the name of a KOM. Maybe it's luck that I don't, I don't know. The guy that died trying to get back his KOM in the Berkley Hills was an idiot of his own accord and an experience cyclist - he should have known better.
I can't speak for other's experiences, but in my own, the Strava hate is way over-blown.
