Author of the article here -- kind of, but the idea here was just to write a piece about a capital-intensive business compared to the couple of capital-light businesses I'd covered in the prior articles I wrote, and how that difference in capital requirements plays through the P&L, balance sheet and cash flow statement. One effect of capital intensity is that EBITDA becomes a less useful measure, sure. Another effect is that the cashflow statement becomes incredibly important to running the business, as does understanding the difference between maintenance capex and growth capex.
