I downvoted you because this has nothing to do with the article. Whether or not Uber is a good thing is not relevant to Kalanick stepping down or the rotten culture he cultivated.
The vast majority of people have been criticizing Uber for breaking laws related to fraud, stalking and harassment, and a generally toxic workplace culture.
The product that Uber offers is good (and no one other than taxi medallion owners is really arguing that). But they've gone about delivering it in an unnecessarily bad way.
