It is increasingly becoming a reasonable prospect to run a home server you can share aspects with other people. If you need extreme scaling because you are hoping to make a profit it won't work. But technologies like Tail scale, docker, let's encrypt and increasingly cheaper low energy but more powerful computers make it a real option.

Even generative AI and LLMs have reasonable results being run on home user gaming rigs and the latest Mac chips.

The author would have had zero problems on a home server sharing a Nextcloud link to just 80 people.

Multiple projects seem to be converging on a single box solution that can be shared, but none are quite there. Tailscale has basically made it zero risk to share to a trusted network. But it would be nice if the Raspberry Pi people or a similar project would be willing to put out something they're willing to stake their reputation on that could be near immediately shareable without opening yourself up to attacks from everyone on the Internet.

I've never been locked out of my LibreOffice documents stored locally on my Linux box.

I mean. Stallman sets a high bar, but to a significant degree it is possible, if extremely inconvenient, to actually take that thought all the way. Whether that's a reasonable decision for the individual is left as an exercise to the reader, and I would tend to be open to other corrective measures, but you can live a life without FAANG.
