Hmmmm, I don't remember it that way. I remember the constant take was to build a moat (typically based on intellectual property), then optimize net profit and/or network effects. Quality never really came up unless it is so bad as to cause lawsuits.
Of course, right after teaching you how to exploit all the bad incentives created by capitalism they teach you that the government is to blame for all bad incentives because capitalism only makes good incentives.
Interestingly, the claim about competing on price was that it would just inevitably lead to everyone lowering their price to zero marginal cost, so you should find other ways to differentiate yourself or to use IP to sue others from not competing.
Let’s say there is a dozen of them playing Minecraft, one could say they are in the same market competing with each other.
But what happens really is some folks like dude with long hair, others like the other guy that screams every time he wins.
Same with training videos, I bought course from a guy that is kind of monotonous and I don’t care but my GF cannot stand watching the guy for longer than 10 minutes.
Bakeries seem like closest one would be best, but somehow I’d rather go 10 mins further because I don’t like the feeling of the first one. Even though quality or price they don’t differ.
I don't mean it in a bad way. I do think engineers and business people should be in contention. But business people will sacrifice product (quality) for profit while engineers sacrifice profit for product.
Quality is often hard to define too. The business people have a harder time defining it as well since they understand at best as a user, but only if they are dog fooding (even engineers often don't!). They've developed strategies to make profit and still be relevant.
