All nonprofitability means is they expect ROI on dollars spent today. In other words a dollar spent today will, in their model, increase their future (discounted) free cash flow. In even more words, profit is when a company runs out of investible ideas (within the assumptions of their hopefully convincing model). The size of the company has nothing to do with it (canonical example is Amazon where you can change the 28M users to at least 280M and rev in the billions).
