This is a question I often have, and I've not come up with a good answer either way. Here are some of the examples I ponder: The modern PC exists because IBM basically spread the knowledge around in their manuals, allowing many compatible devices to be made. In terms of capitalism, this was a dramatic mistake - IBM didn't make profit off of these knockoffs. But had they not, it may well have been similar to Unix (next entry), where many incompatible devices (hardware, in this case, not software) gave a fractured market that just didn't move very far. Unix and related variants - AT&T lost the copyright to BSD because they had failed to enforce it (because that predated the Bourne convention). During the lawsuit, when the future of OpenBSD/NetBSD/FreeBSD was slightly in question, many devs worked on some little toy project known as Linux. Today, we have a healthy market of these open source solutions, but had BSD source not been freely available, would the BSDs have gotten any success? Would Linux exist in its modern form had the BSDs not served to create both a market and supporting software? GNU Herd seems to imply "no". And of course, the Internet - Had some marketing exec been in a position do something about it, the modern Web would never have been created, and the internet itself as something that average people can connect to would be behind a series of paywalls and incompatible standards. Microsoft crushed Netscape, and announced that IE6 would be the "last version" of IE. When Firefox hit a point where it was better, competition was renewed and we eventually moved towards common standards, but that was only possible because Netscape opened their code (and reputation). Other competing browsers had been, but they went nowhere in terms of market share. A few other non-tech examples: Car door handles and mirrors (and etc). If you need to buy a replacement car part, it's ridiculously priced compared to what it is. Why? Because there's very little competition in that market. Even within their own brands most cars have very specific parts outside of the engine. Ideally I'd buy a car that was reliable and had standardized parts - but no such car is available, because the manufacturers not only lack an incentive, they have an incentive to keep it incompatible so they and their partners can enjoy a nice markup on replacement parts. Coke and Pepsi - Between them, they control the vast majority of the soft drink market. But of course, their products are different. Mr. Pibb is not Dr. Pepper, Coke is not Pepsi..People will prefer one or the other, and their preferences won't line up with the corporate owner/controller, and if you have multiple people you are practically guaranteed to have preferences from both brands. Not a problem...unless you want to eat out. Virtually every restaurant (and some universities, conference centers, etc) has an exclusive deal with one or the other. Theoretically we could vote with our wallets and frequent those places that DON'T have an exclusive deal. If you can find any. And if that is more important than, you know, things like food and service and prices.
