Maybe. How many paying customers do you think they have? 1k? 10k? 100k?
I think $40M/year for them would require somewhere between 30k and 50k paying customers.
I suppose we're all just guessing, but when I run the numbers on their business I think that the founders are already millionaires, are on their way to being 100-millionaires, and, when you take into account that when you don't gamble your money away it has a tendency to accumulate and compound, that their model could produce a billionaire over a 20 or 30 year period.
I don't ever read their writing and think that they're jealous of other people's exits. I think they're already filthy rich and they look down on the venture industry in the same way that Warren Buffett looks down on Wall Street.
