The problem is that this deeply held belief in “revenue exceptionalism” over “margin exceptionalism” is a hangover from the industrial era. Unlike industrial era companies, information businesses tend to be deflationary, shrinking the overall revenue of an industry. They also tend to have network effects (and complementary network effects), making them more defensible and therefore higher margin than non tech businesses.
