Great post. In a recent interview this is exactly what Masa Son is talking about: https://www.youtube.com/watch?v=eDpdcWz_F_0 What I don't fully understand - isn't this covered by GAAP accounting in some way?
One of the example of this was Groupon. When they filed for IPO they were using gross sales as their revenue. And then deducting money paid to their partners as expense. SEC had to step-in and ask Groupon to restate their P&L statement so that the top line was net revenue instead of gross.
