Well, Theranos and Etherium are met with frequent criticism on this board with good reason, but the issue isn't about losing out on an investment - which is obviously a risk with any company and clearly not applicable in the case of Uber - but rather, negligent, reckless or fraudulent behavior dressed up in tons of marketing buzz and obfuscated by insane levels of hype that functions only to inflate the ego and perceived prestige of the founders while simultaneously fleecing consumers of their money. The bigger the hype to inevitable-reality gap, the bigger the schadenfreude payoff when the scammer house of cards finally collapses in on itself.
