These freedoms definitely make sense to me. If they were not present we would be living in a very different world where large corporations would keep us in walled gardens and no possible alternative. We would have software available for study but never to tinker with and make something useful.

Its incredulous that I can use a Linux distributions, compilers, multimedia tools and various application for my day to day use; not just a side hobby. You may argue about how good it is, but more or less you would get by. Yet I am not tied to a company with trillions of worth. The development happens in open and its driven by community of developers contributing out passion.

Playsatation and macOS are the examples where companies built heavily out of open source software, but they kept their systems closed. So you can have the code but its not a useful. You still are not in control about how software runs on it. Your only option is to not use it.

I own a PS4 and enjoy it very much. Thankfully its only for gaming, so I am not restricted. I wonder if it was an open platform people would have built many amazing things for it.
