I think some org could take the initiative and offer a standard protocol for "that" to communicate to this service.

Then you could wear something FOSS and clearly not spying, but send some information (if you so wish). Maybe no location, but vitals. Maybe no vitals, but location (suppose you want RFK to see a big "FUCK THE GOAULD" on the map).

Cause when you put enough money into a project, it might actually happen.

This is also the mistake everyone made about platforms and social networks.

I'll repeat again my idea that similarly to Usenet, there should be standard protocols and universal services for a global public system replacing those (Facebook, Reddit, Twitter, Google, whatever). You need a service to store data to be always available - have a standard for that service. You need a service to do some computation - have a standard for submitting a task and storing the result (until retrieved or maybe to the previous kind of service). You need a service to search for objects (common task, yes?) - have a standard for that. You need a service for notifications real-time - have a standard for that too, NOSTR does that now. You need some way to financially incentivize people to provide these services - have a "resource market" service, something like MMORPG item markets (where players script their trade with simple constraints, very easily), to buy&sell space&computation, with payments provided with something like GNU Taler, or BTC Lightning if nothing better. Need common identification - well, there's OpenID, but one can also have cryptographic identities and identity caching services. Need to actually aggregate hundreds of those services for every task - if search service is not enough (suppose we want to also make search and other services somehow partitioned, or something like that, to accommodate for amounts of data), then have an aggregation service (similar to torrent trackers) or maybe just use DNS for that. Structured machine-processable results of those services allow you to never depend on one platform and have everything they offer. With the specific "kind" being provided by the client application.

Humanity in our time has all the technologies it needs and none of the will.
