@signalapp I've read a few replies discussing the open source nature of Signal. I want to help clarify.
Signal (both the client and the server) is open source and libre software, you can edit it as you wish and modify it.
What you cannot really control is the backbone. Unlike decentralized platforms like Mastodon, Signal is centralized.
You can change then compile the client at will, but running your own server will "isolate" you from other users, which is probably not what you need.
Recently, there has been some concerns with US corporations. Signal relies heavily on AWS for relaying the messages. Of course, the cloud provider does not have anything close to identifying users or reading private messages, but they have control over the whole thing.
The catch is that if they decide to increase prices or ban Signal off tomorrow, it will be a huge problem.
But before shouting at the "Nazis" (that term is NOT accurate), let's remind that Apple is a US corporation too. It has massive control over everyone with an iPhone, MacBook or other products.
Many crying at Signal should understand their iPhone is more of a service than an object in itself. One that doesn't allow them to properly install apps they compiled themselves durably, one that locks them into a walled garden, made by a company that has performed censorship over the "App store". In short, a completely proprietary and locked down platform that can absolutely spy on everything you do (and most likely DOES considering NSA Prism ties, which are often forgotten about lately!!)
I don't want to defend Signal right now, as I think that them relying on AWS as a cost-effective/lazy option is okay-ish for them right now, but it can't stay like this, especially with the current political climate.
However, some people should get that their privacy and more fundamental rights are VERY MUCH at risk when stuck to Apple.
Many unfortunately don't listen, but crying at Signal can't save them from the arguably larger issue -- all the privacy and censorship risks that are tied to proprietary operating systems.
