I guess it's not only a matter of revenues. I don't think Uber really cares about divulging revenue - they've done it over the last months for some geographies to prove they're right. I think they care more about where the focus must be = if you're private, you can keep growing without thinking too much about the bottom line/EBIT/EBITDA; when you're public, that's another story, investors (not only individuals) carry about dividends to make their ROI - of course value of the stock is another key element
