There's tons of great free and open source software out there or all to see, use, contribute to, and share. Which is a wonderful thing in its own right, and even more so when you can see the results of what it all produces. I'm typing this on a laptop running Fedora using a web browser called Firefox, on a platform called Hubzilla. That's just a faint scratch of the surface of FOSS and what it's capable of, but it exemplifies how it can become an integral part of daily life, and all without being a pain in the you-know-what to do.
In my quest to get a home server up and running, I began to wonder why every house doesn't have a server in the basement or broom closet holding an entire household's data, communication, and social needs. FOSS is working for me in that regard storing my files and media (via NFS,) providing a cloud service, shared calendar, tasks, and contacts (all via Nextcloud), and hosting an adblocker for the entire network. FOSS provides the alternatives to proprietary services for all these tasks, and in a way that is pleasing to use.
Imagine if all these capabilities came in a ready-to-go box with a simple setup (and ability to be extended.) Is it possible for a box like I imagine to exist? One a consumer can buy, connect to their network, configure in a couple of minutes, and be up and running with a device that puts them in control of their data without having to micro-manage it?
For all the control and privacy protections that FOSS offers, it still stumbles at the convenience hurdle more often than not. Despite growing tech literacy, most consumers do not want to spend the time or the energy doing grunt work to get something working. I don't think this is as a result of choices made by FOSS project's themselves, but rather a symptom of a vast ecosystem that encourages variety but lacks the ability to enforce standardisation in the efficient manner that proprietary software can.
It would ultimately be nice to see an new industry where producers of such boxes can tailor their offerings to consumer's needs, but also retain compatibility. E.g. music lovers could provide built-in streaming server software, and federate the hosted social tools with pre-selected music-related services.
I think it could work given the right individuals and collaboration.
