While it’s popular to belittle business and profit, it’s hard to live on altruism. Would you work without a paycheck? Take your life savings (or borrowing money and committing to repayment) and risk them? Profit comes from taking a chance of increasing that money to cover the chance of losing part or all of it?
I agree with you about avoiding presales in most cases, certainly spending more than I’d be willing to risk if things turn bad, but strongly disagree with knocking business and profit.
