I would avoid it, if you care at all about availability and downtime. The result will probably not be great, you need to ensure the server side gets enough resources under load, and setting it up may require constant restarts if things aren’t immediately working as expected.

Nonetheless, here is a link where someone did essentially exactly that on NixOS: https://astrid.tech/2022/09/22/0/nixos-gpu-vfio/

I didn’t read too much into it, but roughly speaking: Because the technology by design aggregates data immediately and drops any personal identifiers/ the unaggregated data in the process. Other companies can build whatever they want on that, but if done properly, it is impossible to reconstruct user-specific data points and profile the users that way.

This type of privacy-preserving aggregation technique is not new, it is fairly common for things like demographic data, where you want to know things like population density and incomes for some area, without just publishing an exact address with corresponding income for every person (as an example).

Edit: I think I missed your point a little bit. I am unsure, but it seemed that Anonymous is responsible for designing the framework, not doing any tracking (i.e. it wouldn’t necessarily be “put all trust into them collecting it”). Maybe rolling out that technology could be done in a way of blocking other tracking, or maybe it is intended as a basis for regulations to take up. Maybe someone else can give more informed input on that.

I think IPv4+ is what you’re thinking of

There are many ways to contribute. I actually read an article about that a couple of days ago, maybe it will be of interest to you, too: https://github.com/readme/featured/open-source-non-code-contributions

That’s exactly what it is. I haven’t looked into it too much, but as far as I know it’s main advantage is simplifying the setup process, which in turn reduces the chances of a misconfigured VPN.
