Just yesterday, I was trying to explain to my partner (who isn't a programmer) why I think open source software and hardware is so important. My argument is that without enough core components in the industry standard tech stack being open source, the more likely companies who develop solutions will restrict user freedom.
For example, Apple has been able to own nearly their entire iDevice stack from manufacturing to silicon to firmware to OS to ecosystem. They have very little incentive to interoperate with external organizations via open standards because they own many of the pieces which need to be interoperable. Thus, they can force users and developers to use their tooling, the applications they approve of, dictate what code will run on their platform, and how easily you can inspect, modify, or repair their products.
This is all to say, it is easy to imagine a future where all performance-competitive technology is entirely built upon proprietary, locked down stacks – AND – it will be at a level of complexity and specificity that independent people simply cannot gain access to the ability to create competitive solutions. It could be back to the days of the mainframe, but worse, where only the corporations who create the technology will have access to the knowledge and tools to experiment and innovate on a competitive scale.
Amazon wants developers to build solutions entirely on top of their platform using closed source core components. They also want to control the silicon their own platform runs on. In 10 years, what else will they own, how much will this effect the freedom offered by competitors, and what impact will it all have on our freedom to build cool shit?
