Nobody starts a company to target a market with the goal of being replaceable. Let's say you were going to sell cars. Should you publish all your designs and manufacturing techniques so that the marketplace is "fair"?
Cars are replaceable. A few years ago I bought a Toyota. Then I got tired of it so I bought a BMW. No one has me locked in, I'm free to switch. So they have to compete to keep me as a customer (or in the case of BMW to get me back, I was a former BMW driver).
