I'm a big Rich Hickey fan. He's a big user of a (to me) peculiar variant of the phrase, "it ends up": a total of 144 times in https://github.com/matthiasn/talk-transcripts

It also struck me as a bit of a sleight of hand - but maybe it's just rhetorical flourish. Or more charitably you could say it's inevitable - in a conference talk of finite length, you can't possibly back up every assertion with detailed evidence. "It turns out" or "it ends up" are then a shorthand way of referring to your own experience.
