Those are both terrible metrics. They're sensitive to IPO timing, for a start. Facebook is going public very (!) late, it's already achieved market dominance and very significant revenue. Contrast Microsoft, which went up before Windows 3.0, when they were mostly a software supplier to IBM (their other offerings were distant second place products to market leaders like Wordperfect or Lotus).
And "after 3 years" misses a lot of detail too. Apple looks pretty good in that metric. But their "after 12 years" numbers are a disaster. And of course "after 30 years" looks to be pretty fantastic for them.
I'd just like to point out that you are chastising them for going public after obtaining reliable revenues for several years. This used to be the minimum requirement for going public.
Who's chastising anyone? All I said was that they were "late", which is undeniably true. And I tend to agree with you ethically, though that "used to be" leans heavily on "used". Since the PC revolution in the 80's, almost no tech companies have gone public with multi-year profitability.
