Why do you say that, and how does it work? Are you making a completely different statement than the point the parent was making? Sure you usually need to sell something in order to get the profit, but that doesn’t mean that the good or service or it’s quality was prioritized above getting any profit, which is what I think parent was talking about.
Generally speaking, private non-subsidized companies that offer goods and services for sale cannot actually survive without any profit, right? They can bootstrap for a while with investment, but they tend to die, statistically speaking, if they prioritize goods and services over profit. The way companies tend to survive death is by doing everything they can to ensure that the sale of their goods or services generates a profit. You might also be temporarily forgetting that it’s also incredibly common for companies to pivot on what products they make and sell whenever they’re not making enough profit.
TBH it actually seems really funny to me argue about which comes first, because the kind of company we’re talking about needs both, it doesn’t otherwise exist. But the idea parent shared, that profit takes the highest priority, is often absolutely true in practice, many companies will do everything they can to avoid not making a profit, from lowering the quality of their goods and services, to coming up with other more profitable products, to merging with another company that has more customers for your product and/or a longer runway.
