Oh, also, it's a common misconception that publicly-traded companies are required to maximize profits. They can have whatever goals their shareholders want. It's just that the way modern publicly-traded companies work, most of their shareholders are people quickly buying and trading shares based on who they think will earn them the most money this month, so that sort of inevitably becomes the goal of any publicly-traded company.

I've worked for a couple startups and you're absolutely right. If you make a profit you pay taxes on that money, so startups like to spend most of the money they bring in. They also want to show revenue growth, since that's what investors like to see. You grow revenue by getting more paying customers. And you do that by doing what your customers want.

When you go public, your goal is to increase shareholder value. So you do this by reducing costs and finding ways to wring customers out of revenue. You find ways to nickle and dime customers out of revenue so much you develop an entire branch of law devoted to you suing your customers
