Decentralization at the level of protocol--in Mastodon's case via ActivityPub--does not mean decentralization at the level of infrastructural dependence.

2025-10-27 12:01:18 UTC

- reply

I'm sorry if it landed harsh.
First, I don't think not knowing things is inherently bad or shameful--it's where learning starts, etc. Second, there's a misunderstanding here, whoever is expressing it: decentralization at the level of a protocol--ActivityPub or w/e else--is NOT the same thing as decentralization of infra. People running mastodon instances, or Matrix servers, or other fedi systems, are also in most cases leasing infrastructure from hyperscalers to do so.

2025-10-27 11:58:37 UTC

- reply

No, because no modern and useful comms platform provides only text messaging. And if your platform doesn't provide normative features and functionality, people won't use it. And if they don't use it--even if you do--you can't use it either. The network effect rules communications effectiveness.

To conclude: my silver lining hope is that AWS going down can be a learning moment, in which the risks of concentrating the nervous system of our world in the hands of a few players become very clear. And that this can help us craft ways of undoing this concentration and creating real choice ❤️ 13/

2025-10-27 10:41:55 UTC

- reply

So, Signal does what we can to provide a service w integrity in the concentrated ecosystem we're working in. We protect your comms w end-to-end encryption, so that we can use AWS and others as a highway across which to send Signal data in ways that don’t let AWS, or anyone else, gain access. 12/

2025-10-27 10:41:46 UTC

- reply

In short, the problem here is not that Signal ‘chose’ to run on AWS. The problem is the concentration of power in the infrastructure space that means there isn’t really another choice: the entire stack, practically speaking, is owned by 3-4 players. 11/

2025-10-27 10:41:37 UTC

- reply

o, yes, Signal runs on AWS. It also runs on your phone, which runs on iOS (Apple) or Android (Google). And on Dekstop, via Windows (Microsoft). Each of these presents similar dependencies on large entrenched tech companies, and concomitant barriers and risks. 10/

2025-10-27 10:41:29 UTC

- reply

But even if Signal had the billions needed to recreate AWS, it’s not just about money. The talent to run these systems is rare & concentrated. The expertise, the tooling, the playbooks, the very language of modern SRE came out of these hyperscalers, and is now synonymous with 'the cloud.' 9/

2025-10-27 10:41:21 UTC

- reply

Meaning that infrastructure like AWS is not something that Signal, or almost anyone else, could afford to just “spin up.” Which is why nearly everyone that manages a real-time service–from Signal, to X, to Palantir, to Mastodon–rely at least in part on services provisioned by these companies. 8/

2025-10-27 10:41:13 UTC

- reply

Such infrastructure costs billions and billions of dollars to provision and maintain, and it’s highly depreciable. In the case of the hyperscalers, the staggering cost is cross-subsidized by other businesses–themselves also massive platforms with significant lockin. 7/

2025-10-27 10:41:02 UTC

This isn't ‘'renting a server.' It's leasing access to a whole sprawling, capital-intensive, technically-capable system that must be just as available in Cairo as in Capetown, just as functional in Bangkok as Berlin. Particularly given the high stakes use cases of many who rely on Signal. 6/

Instant messaging demands near-zero latency. Voice and video in particular require complex global signaling & regional relays to manage jitter and packet loss. These are things that AWS, Azure, and GCP provide at global scale that, practically speaking, others (in the western context) don’t. 5/

Running a low-latency platform for instant comms capable of carrying millions of concurrent audio/video calls requires a pre-built, planet-spanning network of compute, storage and edge presence that requires constant maintenance, significant electricity and persistent attention and monitoring. 4/

The question isn’t "why does Signal use AWS?" It’s to look at the infrastructural requirements of any global, real-time, mass comms platform and ask how it is that we got to a place where there’s no realistic alternative to AWS and the other hyperscalers. 3/

2025-10-27 10:40:18 UTC

- reply

Concerning, bc it indicates that the extent of the concentration of power in the hands of a few hyperscalers is way less widely understood than I’d assumed. Which bodes poorly for our ability to craft reality-based strategies capable of contesting this concentration & solving the real problem. 2/

2025-10-27 10:40:08 UTC

📣THREAD: It’s surprising to me that so many people were surprised to learn that Signal runs partly on AWS (something we can do because we use encryption to make sure no one but you–not AWS, not Signal, not anyone–can access your comms).

No worries! This means that we, at Signal--the ones developing the app--should be able to opt-out as Signal. To say, "no data access for you, Agentic AI." Instead of leaving that to each person who uses Signal (which invites the issues you rightly name--the fact that one person ultimately makes that choice for more than themselves, in a way that could still compromise their interlocutors' privacy).
